This September we’re excited to again be taking part in the Flood Expo. Held at NEC Birmingham from 14th-15th September, this is Europe’s leading Flood Management event; providing the public with an opportunity to interact with flood professionals, local authorities and communities all in one place, for free. We look forward to attending and engaging with the flood sector and wider public, as well as enhancing our knowledge and understanding of the latest technologies, services and strategies available to help predict, prevent and manage flooding.
What is most special for us about Flood Expo 2022 is the brand new -and first of its kind- Community Flood Zone. This initiative has been developed by Communities Prepared and other flood specialists with the explicit aim of centring the public in the discussion around flooding. It is a space to come with your questions, concerns and needs and help to steer the priorities of the flood services sector and the wider conversation around flooding. The Community Flood Zone will also include :
Mary Dhonau – answering questions and giving practical flood preparation advice using the flood mobile: a ‘flood house on wheels’ that demonstrates various property-level adaptations that can reduce the impact of flooding in your homes and business buildings. Have a look at her website ahead of the Expo.
Flood Re – answering questions and offering advice regarding affordable insurance options and the Build Back Better scheme for those who experience flooding in their homes. Have a look at their website ahead of the Expo.
Attending from our team is Richard Hood, Senior Project Officer with Communities Prepared. Richard is part of the programme’s delivery team, focusing on community development and training. He brings with him specialist knowledge in flood resilience and management, water rescue operations, incident management and operational procedures. He will be available to discuss your concerns and receive your questions on our Community Flood Zone stand throughout the Expo. Beyond this, insight and learning will be high on the agenda with a seminar programme packed with expert-led sessions, panels and demonstrations covering topics from flood reduction to property level flood protection, and a presentation from ITV Meteorologist and trusted voice on climate change, Laura Tobin. Richard will be taking part in a panel discussion as part of the seminar programme too; more details on this to follow.
If you or your community have been affected by flooding, we urge you come to and speak with us at the Community Flood Zone. Your contribution to the conversation is vitally important, and will enable us to continue to develop this initiative beyond this year. The entire Expo is free to attend and both welcomes and depends upon the engagement with the public, so please join us!
Follow the link to the Flood Expo website to sign up for free and see what’s in store, and please share the event with anyone you feel would benefit from it. The venue is wheelchair accessible, easily accessible by train or car and has extensive car parking facilities that you can pre-book. Feel free to contact us with any questions ahead of the event.
We started our roles in January 2020 and the project will conclude in September 2021. We aim to empower communities to take proactive steps to reduce the risk of flood damage to their own properties. We’ve created a project website which hosts a range of online resources, including awareness articles, videos and blogs, downloads, animations and online training. We’re connecting with communities via public presentations and demonstrations and co-developing a community demonstration hub at Wilberforce College in Hull. We’re trying to reach a wide range of stakeholders, including residents and businesses, the property sector and trades, financial influencers and local authorities.
Are there any misconceptions around PFR that you’re looking to address through the project?
We’ve encountered some concerns about the impact of PFR on the appearance of homes and, consequently, their value. Every solution is bespoke to the property. Many of the measures on a property’s exterior are removable and interior adaptations can be incorporated into the design of a home. Once PFR has been installed, it’s the property owner’s responsibility to ensure that it is maintained and put into place in the event of a flood. Some people may be put off by the cost, but it’s important to remember that the cost of repairing your home following flood damage could be considerably more, especially in areas at risk of repeated flooding. PFR is, therefore, a long-term investment, and more and more homeowners are recognising the importance of understanding their flood risk and installing these key measures.
Installing Property Flood Resilience can help to bring peace of mind, whilst also reducing the financial impact of flooding.
All three Pathfinder projects are in close contact and, although we each have slightly different approaches to encouraging take-up of PFR measures, we’re sharing best practice and hoping to put what we’ve learnt individually into some joint projects aimed at raising greater awareness of property flood resilience in other areas of the country during the coming months. We’ve each developed innovative ways of working with our local communities. These include demonstration sites, flood hubs, and online learning with real life case studies, which are soon to be launched.
What are some of the key messages you’ll be promoting?
We’re keen to encourage people to take action to reduce the risk of flood damage to their property. Installing Property Flood Resilience can help to bring peace of mind, whilst also reducing the financial impact of flooding. It’s important to understand the flood risk to your property; so be prepared and act now.
Property flood resilience reduces the damage that floodwater causes to your property and can therefore help to minimise the need for costly flood repairs, saving you money and enabling you to return to your property quicker after flooding. It can also reduce the need to make insurance claims if your property floods. As flood risk is predicted to increase in the future due to climate change, nobody should assume that flooding won’t happen to them. Therefore, it’s important that everyone understands their flood risk and how they can prepare and become more resilient, whether that’s through making a flood plan, considering having property flood resilience installed or making sure that the measures you have are maintained.
How do you hope the outcomes of the project will inform future PFR work?
The learning from our project will inform research into effective strategies to raise awareness of property flood resilience and flood risk. Our work is being used to inform academic studies, as well as educational courses about flood risk management. Through our educational work, we hope to inspire a flood-resilient future generation. We hope that, through engaging with Yorkshire Flood Resilience, more people in Yorkshire will be inspired to make their homes resilient to flooding.

We spoke to Dr Monica Rivas Casado at Cranfield University about the use of drone technology in flood emergency response. Here, Monica discusses their research into the feasibility of using UAVs (unmanned aerial vehicles) to improve mapping of the extent of flooding events. The beginning of this project coincided with the UK winter storms of 2015 which severely impacted Cumbria.
Why was this research commissioned?
Currently, there is a gap in knowledge within the context of flood emergency response that needs to be addressed. In brief, some of the techniques currently used to gather information during and after flood events do not provide all the data required. Flood emergency responders require relatively detailed information on the extent of the flooding and location of properties affected within less than 24 hours. Current methods used to gather data include satellite imagery and aircrafts, which may not provide the required data when there is low cloud cover for example. In the case of SAR (synthetic-aperture radar) satellite imagery (which is able to penetrate the clouds), it is quite difficult to distinguish between water and concrete signatures (i.e. pavement vs. water). We proposed the use of drones to overcome some of these limitations and they turned out to be useful.
What did you hope to achieve through the project?
We wanted to assess the potential of drones to provide information during and after flood events, and in particular how the information could help (i) loss adjusters and (ii) with the uptake of resilience and resistance measures. We collected drone imagery in Cockermouth (Cumbria) after storm Desmond (December 2015), mapping approximately 150 ha. The results showed that we could use the data for both loss adjustment and the identification of areas in need of flood resilience and resistance measures.
Please can you highlight some of the benefits of using drones for flood management, that came out of the project?
Community: Drones enabled
us to identify which properties were flooded and which ones were not, therefore
helping us to establish which parts of the community required more attention
during and after an event occurred. It also helped us to identify which parts of
the community were affected by which types of flooding (e.g. fluvial, pluvial),
which in turn informed flood management decisions.
Emergency responders: The
imagery collected provided detailed information about the extent and impact of
the flood event. It helped detect which areas had been badly affected and
therefore needed more resources during/after flooding. There is potential that
it could help with planning evacuation routes but we have not yet tested that
to the full extent.
Insurance: The images collected enabled the identification of individual properties affected by flooding and, to some degree, the level of damaged caused. This could help insurance companies identify the damaged caused without the need to send loss adjusters on site. If loss adjusters were to be required, the exact properties that they should visit could be provided based on observations from the imagery.
What are some of the general limitations around deployment of drones? How did this impact the project?
Key limitations at the moment are (i) operational, (ii) regulatory and (ii) time processing. We find operational restrictions when trying to fly drones in gusty (stormy) conditions. Drones are not waterproof in general and they cannot fly when it is really windy. This makes operational deployment really complicated during a flood event as we need to find a suitable weather window to start our work. There are also regulatory constraints established by the Civil Aviation Authority. Finally, we are trying to get the drone data collected and analysed within less than 24 hours so that it is useful for emergency responders. At the moment, it takes longer than this to generate the first results so we are now exploring the use of machine learning techniques to be able to obtain the outcomes that we need on time.
We experienced all these limitations when undertaking the project but managed to overcome most of them through good planning and carefully thinking about the logistics of the mission. For example, we overcame the regulatory limitations through close liaison the CAA and on-site emergency responders.
What was the impact of the research at the time?
We managed to collect a very comprehensive data set of the area and demonstrated that the data collected could be useful for flood management. There had been flights undertaken in the past with drones over flooded environments but, as far as we know, the data sets collected were not as comprehensive as the one we captured. We understand results from the project have been used by governmental agencies to make informed management decisions.
How do you see drone technology developing on a wider scale, both nationally and internationally?
I believe drone technology will be adopted across the country as an additional tool to inform the extent and impact of flood events. Their use has already been adopted by the Environment Agency across England and is expected to increase in the future. The potential of the technology is still yet to be fully explored, but initial results show promising applications at a national and international level. For example, we are currently assessing their potential for flood emergency response in India where flood events affected large parts of Kerala in the summer of 2018.
What future related projects does Cranfield University have in the pipeline?
We have multiple on-going projects on the use of drones for flood emergency response and the uptake of resilience and resistance measures, the details of which are published here. We are assessing their potential for the real-time planning of flood evacuation routes and looking into the use of machine learning to speed up the processing time. Aside from the use of drones but still within the context of flooding, we are working on (i) how best to communicate flood risk to different community groups and (ii) determining who would be best placed to communicate this message. This will be published in due course.
Finally, what was your personal highlight of the project?
A highlight for me was around the logistics of deploying the drones after a flood event. It required liaison with the CAA, Army, drone pilots and emergency responders on site, and helped me understand how emergency responders operate during and after a flood event from an in-field perspective.

In my experience, flood risk management is a jigsaw of many pieces, all working together on reducing flood risk (such as flood warnings, municipal flood alleviation schemes, natural flood defences, temporary barriers, sustainable drainage, etc.). In the last few years, due to intense and prolonged rainfall, we have seen robust defences over-topped and breached. What can we do at a property level to reduce the appalling impact that being flooded brings with it?
I have been flooded myself, so I know only too well just how awful it is and how long it takes to get back to ‘normal’ again. We can, of course, think about using property flood resilience products (PFR) to try to keep the water out and help to give extra time to move precious belongings to a place of safety. I know people worry about labelling their home at risk of flooding, but that doesn’t have to be the case. ‘Flood doors’ look just like a normal doors but once locked can withstand flood water to about 6m. Airbricks can be replaced with a ‘self-closing’ variety which can stop an awful lot of water entering into a home. Non return valves fitted into drains can stop sewage entering homes via toilets, showers etc. Always look for products with a kitemark, as they have been through a robust testing procedure. There is more information about risk reduction products here.
The average amount of time it takes to repair a property is about 9 months, and that causes terrible disruption to life as we know it.
If you are flooded, work with your insurance provider to ‘build back better’. By this I mean adapting your home/business to help it to recover more quickly, should you flood again. The average amount of time it takes to repair a property is about 9 months, and that causes terrible disruption to life as we know it. Moving electric sockets and services up the wall, using waterproof plaster, tiling floors and fitting a flood resilient kitchen (which doesn’t have to cost much more, or look ugly) can help reduce the damage a flood does and speed up the time it takes to recover, allowing you to get back home sooner. Over the past year, I have travelled around the country and talked to people who have taken steps to both try to keep the water out and also made adaptations to reduce the impact. Do have a read of their stories and see how beautiful their homes and businesses look.
In 2017, I project managed the retrofitting of two properties, a community centre and a private home, to help them to recover more quickly if they flood again. The details of the project can be seen here. Again, you will see how beautiful the properties looked, once the work had finished. The EMag also details the products used.
Protecting our homes from burglary and fire has become the norm. My hope is that reducing flood risk, at a property level, is treated in the same way.
With the threat that climate change brings, sadly flooding is going to become more frequent and more damaging. It is impossible to stop floods from happening, but we can do our best to manage flood risk. Protecting our homes from burglary and fire has become the norm. My hope is that reducing flood risk, at a property level, is treated in the same way. It may also lead to reductions in the price we pay for flood insurance, as well as peace of mind. Working in partnership, we can reduce the awful misery being flooded brings.
