Let's get serious... and game!

by @SeriousGeoGames (aka @CloudSkinner)

Writing this blog post comes at an exciting time for me. I've been working on a project called 'Humber in a Box' with a group of student developers from SEED (a software development group at the University of Hull), and it is going to make its debut at the Hull University Science Festival this coming weekend. Humber in a Box represents a start for me at looking at using gaming technology and ideas to better communicate research, and I am going to use this post to explain the ethos behind this.

Think of gaming, whether on a table, a board or a computer, and you probably won't think about learning. After all, games are supposed to be fun, they're supposed to be entertainment. Learning is not often portrayed as fun, although us academics would take you to task on that. These two things, entertainment and learning, are seldom thought of together outside the use of jargon, like info-tainment or edu-tainment, and things that tend to use these labels are also seldom both.

It is my belief that games can be different, and as Geographers we can use gaming as a tool to educate and to communicate our science. What a game can do, which almost no other medium can, is put a person in the shoes of someone else, place them in a situation (metaphorically) where they have to react or behave in a way they would not normally have to, and through this experience a new dimension to a problem or issue.

For instance, a simple game to run in a classroom would be a debate where opposing sides have to assume certain roles. One I ran recently involved a debate about hydraulic fracturing, or "fracking", and split the group in three. Group 1 were to be the developers, who wished to explore the shale gas reserves beneath our Geography Department; Group 2 were an environmental pressure group determined to put a stop to this; and Group 3 were those in the Geography Department who would make the decision. Groups 1 and 2 were armed with the same crib sheet of basic facts and some case studies, and each group was given 30 minutes to discuss and research, before Groups 1 and 2 presented their case.

Hydraulic Fracturing, or Fracking, is a controversial practice ideal for classroom debating games (image by US Environmental Protection Agency).

Despite the best efforts of Group 1 to reassure the decision makers, Group 3 voted unanimously against the development. This was also against the group's general support of hydraulic fracturing outside of the game. The purpose of the game was to show that a contemporary issue like this requires both a Human and a Physical Geography response to fully understand it, and how researchers from both need to engage with it and work together. It also highlighted the difficulties of communicating science and research in a live, ongoing debate with many emotive issues also going on (often of far greater importance to the members of the public involved).

The above example is a very quick and simple game that is often used (often without the realisation that what is going is in fact a game), and it is those same principles that can be taken forward and combined with modern and emerging technologies to create something more powerful.

This could be a physically constructed object, like the 'River in a Box' that we have at the University of Hull. This table is boxed and filled with sand, with water pumped into the top allowing it to flow over the surface and down the slope. It is a miniature version of the big flumes used in physical modelling experiments, such as the Total Environment Simulator at The Deep. As the water flows it erodes the sand and produces channels, like a river, only smaller and quicker. On this you can place model houses and let people model defences, or artificial channels, with their hands. It is a very simple, yet very effective way of communicating various aspects of river science, such as geomorphology, flooding and erosion.

There is so much that can be done by tapping into the potential of computer gaming. The gaming industry is worth £59bn worldwide, which is more than the music and film industries, and it is still growing rapidly. It is massive business and it has a huge user base. It should be obvious from the popularity of games like SimCity, Civilization and Minecraft that there is an appetite for games with a learning angle, if they are done correctly.

Researchers at Hull are already on the curve when it comes to Minecraft. The HullCraft project, run by the University and Hull History Centre, in particular Joel Mills and Hannah Rice, looks to rebuild some of archived architectural plans in the History Centre within the Minecraft engine by enlisting the help of users, many of them young. People take part as it is enjoyable and they can earn badges to display on online profiles, but they learn about the history of Hull and about architecture as they do so.

This is why I started SeriousGeoGames (SGG). I'm not sure what it is just yet, a project I guess is the closest word. I'm not even sure that this rather dull, yet descriptive, name will be its final moniker. It is, however, a medium I am using to explore the potential of modern gaming technology, and other cool pieces of tech, to be turned to a good pedagogical (posh word for teaching style) use. It is very early days, but the first project is underway working with a group of student developers from the University of Hull's software development group - SEED.

The project is named 'Humber in a Box' and is using our CAESAR-Lisflood model of the Humber Estuary and placing within the Unity 3D gaming engine. Via an Oculus Rift virtual reality headset, the user is put inside the model viewing the topography of the surrounding area in three dimensions, and has the ability to fly around using an Xbox controller. In the background the model is calculating the tides within the estuary and graphically displaying these. To help communicate the dangers of future sea level rises without investment in flood defences, there is an option for the user to increase the water levels up to whatever level they like - but it gets very wet after 5 m! The science behind this is based on the paper featured in this previous blog.

All these cool toys are great but the danger is that they don't transcend that to become more than just toys. The ethos of SeriousGeoGames, whatever becomes of it, will be the communication of the science and research that went into making it. I hope this has given you some introduction to the use of gaming in science and learning - I'm not claiming that this is anything overly new or innovative that I have come up with (not by a long shot!), so, with that in mind, below is a blog roll and twitterati of interesting things to follow (please feel free to comment and suggest others that should make the list -

Storm Surge 2013 : One Year On - Part Four : Spurn

by @cloudskinner

This is the fourth and final installment of our mini-series looking back over the year since the 5 December 2013 storm surge, which flooded many areas in the Humber Estuary and along the east coast of the UK. The first part, Modelling the Surge, looked at the research that has been conducted since the storm surge and has advanced our knowledge and understanding of these events in the Humber. Part Two, What we Learnt, focused on the 2014 Humber Conference and the lessons that have been learnt over the year. Last week guest blogger, Jazmin Scarlett, told us about some of the often unseen impacts of flooding, the mental health issues that can arise, and how communities band together after disasters.

For the final part I want to take a longer look into the future and try and predict what it has in store for Spurn. Spurn, or Spurn Point as it is commonly known, is a piece of land that resembles a spit, sweeping out from the edge of the Holderness Coast and round into the estuary. It is important for several reasons: it hosts the signalling station for the Association of British Ports (ABP), kind of an air traffic control but for shipping; it is home to lifeboat crews (formerly permanently, with their families, but now just the crews whilst on shift), providing them quick and easy access to the North Sea and the estuary; it is an important site for migrating bird life, being a National Nature Reserve owned by Yorkshire Wildlife Trust; it keeps the mouth of the estuary narrow – it is not known what effect a wider mouth would have but it is expected that it could lead to a narrower channel with implications for shipping; and finally, it acts to guard the estuary from the full ravages of storms and waves.

When evaluating the true impact of the 5 December 2013 storm surge one cannot ignore Spurn. One of the most dramatic scenes from that night was the damage done to the landform, as highlighted in the LiDAR images below.

The breach at Spurn as shown by LiDAR data. Light Detection and Ranging (LiDAR) techniques uses rapid pulses of laser light to measure the elevation of the ground, both rapidly and in high detail. The top image shows the breached section of Spurn before 2013, and bottom image shows the same section measured shortly after the 5 December 2013 event 

(LiDAR data collected and provided by the Environment Agency).

It is clear that extensive damage was done by the waves and high water levels during the storm surge. The water will have over topped the narrow spit of land that separates the sea from the estuary, and washed the embankment down towards the estuary – you can see in the image that the bank has gone, and a mound of material has built to the left, on the estuary side.

There once was a road here at the breach site 

(author's own photo taken November 2014)

To understand the implications of this, and what the future might be, we need to delve into the past of Spurn. There are two theories behind the formation of Spurn which have emerged from two former University of Hull academics -

1. George de Boer long maintained that Spurn was a spit – material eroded from the Holderness Coast washes down via longshore drift, and is deposited as a long spit in the form of Spurn. Over time as the coast line retreats, this spit will be rapidly destroyed and another will form further back in line with the coast.
2. John Pethick disagreed however – He argued that Spurn was not a spit as such and had not retreated over time through repeated cycles of destruction. Rather, the end of Spurn is an island and had been in a fixed position throughout history, whilst the area between the island and coast is in a constant state of flux, sometimes forming a spit, sometimes a chain of islands and sometime open channel and sand banks. Although the location of this region has shifted over time with the coast, the end of Spurn has remained.

Until the 2013 storm surge both these theories were just academic. In his chapter of Neale and Flenley’s 1981 book, ‘The Quaternary in Britain’, de Boer recounts the recent history of Spurn and tells a tale of how it became a very man-made feature. He claimed that a cycle of destruction was taking hold in 1849, initiated by a violent storm (probably not unlike 5 December), and within a few years several wide and deep breaches formed along the narrow spit as it were then.

In response, and to maintain the lighthouse and lifeboat crews housed there, the government at the time funded works to fill the breaches and huge loads of chalk from Barton-upon-Humber were dumped into the channels to fill them. Spurn came into the hands of the military and prior to WW1 the defences were bolstered and groynes put in place to let the spit grow. During both World Wars Spurn played an important role, not least in monitoring for possible enemy U-Boats infiltrating the estuary. It even had a railway line until 1951, and withstood the infamous 1953 storm surge with little damage.

In the 1960’s Spurn passed from military hands into the Yorkshire Naturalist’s Trust and eventually Yorkshire Wildlife Trust’s ownership, and the focus shifted from maintaining the hard, man-made structures of Spurn to the conservation of its environment and wildlife – as such the investment and work done to retain the defences has significantly decreased. I am sure George de Boer, if he were alive today, would suggest that the breach is the beginning of the cyclic destruction of Spurn that was stalled in the 1840’s.

I’m more inclined to side with John Pethick, however. Even if we were to just let nature take its course, I cannot envisage Spurn being utterly destroyed and replaced further into the estuary, nor do I think the evidence is strong for that having happened in the past, but it is clear that without huge investment to rebuild the spit as it were before 5 December, the nature of Spurn is going to change and will be in flux.

To predict what will happen to Spurn in the future, as the Holderness Coast retreats further back and sea levels rise, we need to adapt our models to be able to simulate some of these scenarios. Equally, it is important that we turn again the research of George de Boer and John Pethick, dig even further and try to understand the nature of Spurn; what it is, how it formed and how it has changed naturally in the past. Understanding that is the key to understanding its future.

Storm Surge 2013 : One Year On - Part Two : What we Learnt

by @cloudskinner

This is the second post of our mini-series about the 5 December 2013 storm surge, and its legacy for the Humber region in particular. Last week's post highlighted some of the research that had been undertaken after the surge, and why this is important for understanding the future flood risk in the Humber, especially in the context of climate change which is predicted to bring bigger and more frequent storms, as well as a steadily rising sea level. This post looks at what we have learnt about the storm surge a year after the event, and summarises the presentations given at the 2014 Humber Conference held at Hull's Guild Hall in mid November, organised by the Humber Nature Partnership. You can view individual presentations using the links on the presenters' names.

Dr Susan Manson from the Environment Agency (EA), a co-author on the research highlighted last week, began the conference by providing some of the key scientific details about the storm surge. It has commonly been held that the devastating 1953 storm surge was the baseline for these events in the Humber - the 2013 storm surge is currently the largest on record, but there have been five other events larger than 1953 in between. The fact that the devastation and loss of life has never been as extensive is true testament to the defences and plans that have been invested in since that time. For the recorded tide from the EA gauge at Immingham, which has been recording since 1963, 2013 was the highest ever water level, and by some margin.

Susan gave some figures about the surge. 116 flood warnings were issued. 1,170 properties were flooded around the Humber estuary, but the defences protected a staggering 156,000 further from the surge. It normally takes a tidal crest more than an hour to propagate from Spurn Point, at the mouth of the estuary, to Blacktoft Jetty along the River Ouse, but the surge covered this distance in just 15 minutes – described as “like a wall” by some.

40 km of defences were overtopped but most of them held, with only two points where the flood defences themselves were breached (south of Cleethorpes on the south bank, NE Lincolnshire, and near Skeffling, on the north bank, E Yorkshire). The EA has been busy strengthening and repairing defences as fast as they can. Philip Winn of the EA described how they are using X-Rays to check the integrity of defences to ensure they are up to standard, and how the defences at Alexandria Dock have been improved (all of the flooding in Hull City Centre emerged from overtopping the 1 km stretch here). Phillip also described how the EA are looking to the future, reconsidering the Humber Strategy drawn up before the flood and going to the Government with a request for £1bn to upgrade the estuary’s defences to a 1 in 200 year standard.

But for many people the misery of the storm surge continues. One of the worst affected places is the small town of South Ferriby on the south bank. The defences overtopped and flooded the majority of the houses there and depositing large quantities of silt and mud inside. One of my old school friends described on Facebook how she sat on the stairs watching the water rise as her children slept upstairs. For many it was over 6 months until they could move back into their houses.

The Cemex factory was very badly damaged and a full year after the flooding it still has not returned to production. Kevin Groombridge of the firm described how the flooding did not just bring water, but also sediment and salt. These clogged machinery and corroded the electrics of the site, which were all at ground level. Having never flooded in 75 years they nearly did not heed the flood warnings from the EA, but the Director of the site insisted the workforce move. It is possible that he saved numerous lives by that decision and thankfully that is just speculation.

Kevin described how immediately after the flood a ‘Blitz-spirit’ emerged among the staff, and how the factory manager had to buy new office furniture, laptops, stationery and even diesel generators on a credit card in order for them to continue working. Literally everything on the factory site had been destroyed.

Agriculture was also badly hit. Andrew Wraith of Savills UK, an Agribusiness, described some of the impacts that has struck them. On their Yokefleet Estate they have 34 residences and 22 of those flooded, and 1000 acres of their 2500 were flooded to a depth of 4 ft., and a green pea factory was flooded. Some of this land was flooded for 2 -3 weeks but was alleviated by pumps. A major issue they faced was soil erosion caused not by the flooding but the speed of the water draining away.

They lost many crops, both planted and stored, and Andrew put the cost of these losses in seven figures. But Andrew also said that they considered themselves lucky – when the surge hit they anticipated that their crop loss would be almost 100% but it was actually a loss of 5-10% of the yield. He put this down to the dry conditions prior to the surge allowing for effective drainage of the damaging salt water. The timing of the surge was also fortunate, as had it had been in the spring or the summer they would have felt a two year impact on yields.

Behind Hull's Tidal Barrier on 5 December 2013 - It the water level came within 40 cm of overtopping (by @Tom_Coulthard)

And it is this sense of being lucky that I want to end this post on. If you were one of the residents in South Ferriby, out of your home for the better part of a year, you will not feel lucky, and you weren’t. If you live in one of the 156,000 properties protected by the EA’s defences, a product of decades of work and investment, you were also not lucky but fortunate that we have invested in our excellent EA. But in many ways the Humber estuary could be described as being lucky as stories emerge of near misses and close calls. It was probably only the decision by one Director at Cemex that saved the lives of their workers. The tidal barrier at Hull came within 40 cm of overtopping and putting at risk hundreds of properties along the River Hull – if the surge was timed with the high tide, rather than 2 hours apart, it could have made the difference and spilled over. If the weather in the prior days had been wet then the salty flood water would not have drained as quickly as it did, this fact saving much farmland and properties from further damage.

In all the defences of the Humber were put under considerable strain by a massive, unusual, and largely unprecedented event, but came out on top. Just. Those responsible for them should be praised that they withstood the barrage, and that there was no loss of life. But we should not become complacent – we may never witness another event of that scale again in our lifetime, but as our climate warms, becomes stormier, and the sea level rises, the chances of another, or larger, storm surge in the Humber increases. We need to continually work to keep our defences ready.

Storm Surge 2013 : One Year On - Part One : Modelling the Surge

by @cloudskinner

This is the first post of a four week mini-series looking back at the storm surge of 5 December 2013. The surge caused extensive flooding along the East Coast of the UK but our focus has been on the area immediately around the Humber, and you can read our reaction shortly after the storm surge in this older post. Over the next few weeks we will be discussing the research that has been ongoing since the event, how it affected and continues to affect local residents and businesses, the community resilience that has been built and finally we consider the damage done to Spurn Point and its potential future.

This week the focus will be on a paper recently published by myself, colleagues at the University of Hull, the Association of British Ports (ABP) and the local Environment Agency (EA), which stemmed directly from the storm surge. The paper is free to view until 28 March 2015, after which you will require a subscription to Estuarine, Coastal and Shelf Science to view.

Hull's flood defences overtopping on 5 December 2013 (by @tom_coulthard)

Estuaries are very complex environments. There is a lot going on, beginning with the inputs of often several rivers, and the sea in the form of tidal flows. The relative influence of these on when and where the water and sediment moves in the estuary depends on the tidal cycle and the discharge levels of the rivers. It is a to and fro tug of war between these for influence within the estuary.

If that was not complex enough, there are secondary flows within the estuary. River water is fresh and sea water is salty, making the two flows a different density along with water that is mixture of the two in between. The two water types are often different temperatures too, again resulting in different densities and inducing flows from more dense to less dense regions. All of the flows are influenced by Coriolis forces, the deflection of water flow caused by the rotation of the Earth. The shape of an estuary also influences flow, and in combination with the influences above, estuaries like the Humber often show two channels along the bottom - one resulting from tides coming in and one from tides going out. Finally, overlain on these are the winds, waves and pressure influences of the weather.

This makes estuaries very complex and turbulent, and this turbulence can form a layer of thick sediment laden water to form along the bed - this basal mud layer clings to the bottom and effectively lubricates water flows along the estuary and shields the bed from erosion and deposition.  The salinity of the water also causes fine sediment to clump together in a process called flocculation which makes them behave like larger sediment particles.

It is commonly thought that to model the processes in an estuary then you need to account for all of these processes, but doing so is incredibly computationally expensive. It is possible to do, but even on expensive and powerful machines it often takes several days to model a single tidal cycle. Trying to use them to predict the future of an estuary several decades in the future would be almost impossible. Our approach was to use a simpler model, CAESAR-Lisflood, which has been widely used for a similar purpose on rivers for over a decade, to try and model the Humber Estuary successfully without all of this detail.

Animation showing the CAESAR-Lisflood model simulating the 2013 storm surge and associated flooding.

It was during this process when the storm surge struck and the focus of our research switched. We had already tested the model's ability to reproduce tidal flows - rapidly and at small timescales - so we soon tried applying the data recorded by ABP during the surge. This showed that the model could also reproduce the location and extents of the flooding on that night. This was using the latest information on the Humber's flood defences provided by the EA. The quickness of the model to process the data would make it suitable for producing numerous possible scenarios based on live and forecast data, and potentially help predict the extent of future flooding before it occurs.

This work is ongoing. Next week I will highlight how local residents and businesses were affected by the flooding, as discussed at the Humber Conference of December last year. If you wish to view this paper you can do so here.

This City Belongs to Everyone

by Chris Skinner

Recently, I was tasked with designing five workshops for our Foundation Science programme to introduce Geography specific material to those students planning on studying it in the future. For one of these workshops I plan on looking at our city, Hull, and its surrounding area, asking how, as Geographers and researchers, we can get involved in understanding and influencing these. I want to demonstrate to my students that whatever your research area you can be invested in your local area.

I began by hijacking a Departmental staff email discussion to ask "what do you consider to be the most pressing geographical issue facing Hull?", and I found the responses interesting, highlighting how different research specialisms cause people to think of our local area in different ways. So interesting, I wanted to share some of the responses here with you.

Myself,  I would say flooding and the increased pressure caused by rising sea levels. This was shown clearly by the storm surge of December 5th 2013 - the tidal barrier at the mouth of the River Hull had just 40 cm left to spare and the minimum sea level rise predicted by the IPCC to 2100 is 40 cm. Obviously, the city will need to invest in better defences or other solutions. I wrote about this in a previous post.

In mainly short replies, several of the Physical Geographers here agreed in their responses -

"Flooding!" - Professor Lynne Frostick

"Climate/Environmental change, sensu lato." - Dr Jane Bunting

Professor Jack Hardisty, however, saw an opportunity to establish the city as the heart of the "Energy Estuary" as the most important issue. Many agencies are working very hard and with great success to create a hub of sustainable energy in the Humber, both in the construction of infrastructure (like the development of the Siemens off-shore turbine factory in Hull), and the generation of power, such as tidal generators.

Professor Jeff Blackford suggested "Economic inequality and lack of social mobility" to be the big issue, and he was supported by many of the Human Geography researchers.

“A combination of its structural economic legacy, urban austerity, and environmental situation” - Professor Andy Jonas

“Flooding and relatedly, the feeling that the place was abandoned and left to rot in the aftermath of the 2007 floods.” - Dr Briony McDonagh

I like this quote from Briony as it highlights how the issue identified by the Physical Geographers, the flooding, is intrinsically linked to those emerging from the Human Geographers. The flooding in 2007 needs to be understood in the physical sense to find out what caused it and how it can be avoided in the future, but also the impacts on people and their perception of the city and its place in the country needs to be understood. I find Hull has a sense of abandonment by the rest of the country that was either started or was reinforced by the bombing during the Blitz (and subsequent lack of reporting) - this same sense emerged post-2007 that the city was ignored in favour of other areas after the flood. Indeed, the major flooding on the 5th December 2013 slipped under the nation's radar somewhat too.

The National Film Theatre on Beverley Road was listed in 2007. It was bombed and burnt out in 1941 and was never repaired - it is one of the last remaining visible bombsites from the Blitz.

“The challenge of overcoming Hull’s negative (and inaccurate) imaginative geographies – on the receiving end of too many Hull or Hell jokes…” - Dr Suzanne Beech

However, one issue raised by Professor David Atkinson provoked a discussion. Here's his full response -

“The effects of the city of culture award before, during and after 2017

Hull as an under-bounded city (and current wrangles to fix this)

The elusive nature of place and ‘Hullness’”

A different resonance - Whereas the rest of the country had iconic red phone boxes, Hull's were white (although the tourist office still sold red phone box souvenirs)

(Image by RM21, from en.wikepedia under Creative Commons Licence)

I want to pick up the issue of Hull as an under-bounded city. What does this means? It is down to the way the city boundaries are drawn that exclude some of the sub-urban areas around the city, like Cottingham and Willerby. These areas are more affluent than much of the city and are not included when drawing statistics for the city, or contributing towards Council Tax to run the city's services (which many of the residents in those areas will use). This is a relatively uncommon situation and negatively skews many of the statistical indices for the city and reinforcing its negative reputation in the country. There are plans to rectify this, but as you can imagine it is not popular in those areas that may go from being within the East Riding of Yorkshire region to being with the City of Hull.

Professor David Gibbs also felt this was the major issue and highlighted some of the controversy, suggesting that this would be an interesting topic to look at as part of a workshop.

“I agree with [Professor Atkinson], the under-bounded nature of Hull and the debates between Hull and the [East Riding of Yorkshire] would be good and lots of on-line debates to tap into on press websites – see the Hull  [Daily Mail] website for a good deal of lively debate in the comments section!"

This issue was also picked up by Dr Kevin Milburn. Here is his full response -

“For a long time it seems the city’s location has been a handicap (or at least perceived as being such), to which I must also lob in the relatively poor transport connectivity of the city, especially to other cities and towns in the North. It feels like it would almost be quicker to get to, say, Grimsby or York, by unicycle than public transport. Now, however with renewed interest in the opportunities offered by the estuary, most obviously demonstrated by the recent Siemens investment announcement, perhaps Hull’s peripheral location might actually start to be something of a plus point. The city’s isolation/'end of the lineness’ – and supposed subsequent uniqueness – was interestingly used as a positive by the Hull 2017 bid team.

I also agree with the points raised re. Hull’s boundary and the impact this has on where Hull finds itself on national league tables re. schools, poverty, unemployment rates etc. I find it bizarre that somewhere like Romford can be considered, administratively at least, part of London (it doesn’t get more Essex!) and yet Cottingham, for example, is not part of the Hull metropolitan area.”

David Atkinson raised further points that might contribute to the sense that Hull is dislocated from the rest of the country, something picked up above by Kevin - 

"- a lack of central government funds to assist with reconstruction after the war

- the sudden collapse of the fishing industry in the 1970s and 1980s, and the failure of national government to protect Hull's interests (as perceived by the locals)
  
- the decline of some other, traditional, heavy industries with limited central government assistance in the 1980s-2000s

- the rising sense that other cities and regions could sneer at Hull (reaching its height in the 2003 'Crap Town' accolade)"

I found this exercise really interesting and really insightful, and I look forward to seeing how the people involved above shape their future research in order to investigate the issues they've highlighted. I can't speak for the others, but I am sure it is true, but I love this city, my city, and whilst we're not blind to its issues and problems, we embrace its wonderful character and personality which, honestly, is unlike anywhere else in the world - that's partly why we won, and were so proud to win, the City of Culture status for 2017. Nothing sums it up better than the bid video - This City Belongs to Everyone.

I think my students are going to find the responses useful and I plan on having an enjoyable and lively discussion about them during the workshop.

The Surge 2013

by Chris Skinner (@cloudskinner)

This blog post is going to talk about the storm surge that swept along the east coast of the UK on the 5th December 2013, last week. Rather ironically, I was going to post about problems in predicting disasters and how we mitigate against these, but this seems more topical and worthy of a post., and I hope to give you a bit of an insight into how a GEES researcher responds to live events relevant to their field.

The surge seemed to catch everyone by surprise. I checked the forecast on the Monday as my in-laws were travelling to Hull from London to visit us on the 5th, and the Met Office app suggested Thursday was going to be quite nice, but a bit windy in the far North-East. The forecast did evolve over the week, but not so much to suggest the conditions that resulted in them passing at least five overturned lorries on their journey (two and a van on the Ouse bridge alone).

On Thursday afternoon, there were warnings of a storm surge – a temporary increase of sea level caused by low pressure and high winds – that would potentially flood coastal towns on the east coast. Our local news focussed on Grimsby and Cleethorpes as being the most likely to be hard hit. Hull was just at medium risk. Myself and Prof Coulthard (my boss) watched the tide rise on the Immingham tidal gauge and compared it to the data we held from the same site during the 1953 storm surge.

The 1953 storm is THE storm when talking about storm surges in the UK. It was big and it caused extensive damage and over 300 people lost their lives. This storm was being billed as ‘the worst since 1953’, yet to our astonishment we saw the tidal gauge go up and look increasingly like it was going to exceed the level recorded back then.

As we were leaving the office, around five thirty, the first warnings started coming in that Victoria Dock in Hull was at risk. I followed the story unfold on Twitter as photos popped up showing the first signs of water overtopping the defences. The Marina also flooded and water spilled out into the Kingston Retail Park, and the home of the Hull Stingrays and Hull’s most versatile venue, the Ice Arena.

The City of Hull held its breath as high tide approached. Only the tidal barrier stood between the surging sea and thousands of properties in the flood plain of the River Hull behind. The tide crept ever upwards, lapping at the sides of the mighty barrier but could not overcome it. But it was close – only 40cm remained of that barrier, built to defend the city after the1953 surge. It had done its job, just. The tide height of 5.8m is a record high for Hull.

The sea water eventually receded at Hull.  High tide was later in the inner estuary and badly flooded South Ferriby and Goole. The flooding continued further south, in Skegness and Boston. Another great tidal barrier, the Thames, was also needed to save large areas of East London.

Now that the waters have passed the data is beginning to be collected and analysed. What seemed to take everyone by surprise was the scale of it. Data from the Immingham gauge stopped when the level reached 8.5m*, but from the curve it looks like it would have continued to around 9.5m – 2m above the predicted astronomical tide (from the pull of the Sun and Moon), and over a metre greater than the highest reading from the 1953 storm surge (at 8.4m).

*I don't know why the gauge stopped, most of them did before high tide that night. My guess is that they either reached the top of their scale, or exceeded a threshold where it is assume too high to be accurate - The Immingham gauge stopped at around the maximum of the 1953 tide level.

This is very significant. I don’t think anyone anticipated it. As I said previously, 1953 was THE storm. For the last few months I have been working on a computer model to simulate the flows in the Humber, with one of the aims to be able to predict the estuary’s response to 1953-like events, especially in the face of rising sea levels. Much of the Humber’s defences were built after the 1953 surge so unsurprisingly the model showed they coped well. Our hypothesis was that the rising sea levels on top of that might cause them some issues, so we wanted to try and model that.

Naturally, first chance on Friday we ran our model with the tidal heights recorded on the evening before. Our model suggests that if we had been able to predict the scale of the surge we could have anticipated the flooding, even just based on this preliminary data (although a large pinch of salt is needed when interpreting the simulation below).

As bad as the flooding was, it has to be said that our infrastructure did a fantastic job. The scale of this surge was unprecedented, quite a bit bigger than 1953, yet there has not been the devastation, and thankfully, the loss of life that followed that storm. If it were not for structures like the Hull Tidal Barrier, it would have been much, much worse.

And that leaves us with a warning. The International Panel for Climate Change (IPCC), uses different models to try and predict future sea level rises for the next 100years, and the 'Best Case Scenario' - where greenhouse gas emmissions are cut immediately - would likely cause a sea level rise of 40cm. This is the capacity left over on the Hull Tidal Barrier. When we consider that an increase of 60-80cm is probably a better estimate, the ability of our infrastructure to manage this size of event in the future needs to be considered. It maybe that this storm surge is an event that won't be repeated in our lifetimes, but it now stands as THE storm we’ll be using the measure future resilience and it pushed us right to the edge.
