Improving future flood resilience

iCASP will be involved with the new ‘Yorkshire Future Flood Resilience Pathfinder’ project led by City of York Council which won Government funding last week.

The project involves several iCASP partners including City of York Council and the Environment Agency and will encourage greater uptake of property flood resilience (PFR) measures across Yorkshire. It will draw upon existing projects and initiatives tackling flooding in the region and share best practice and provide training.

One of the more exciting aspects of the project will be the creation of a physical demonstration site in the form of a community hub and learning lab at Wilberforce College, Hull. The learning lab will have exhibits, physical models and demonstration PFR measures used to deliver training and awareness raising to a broad range of other projects, communities and people.

The Living with Water Partnership, who recently started an iCASP project on telemetry integration, will co-develop the learning lab and continue its management and delivery beyond the end of the pathfinder funding.

iCASP’s role in this pathfinder project will be to review the current awareness and adoption of PFR measures in communities and businesses across Yorkshire, and also across local authorities, planners and other professionals who promote, procure, design and deliver PFR interventions. This will take place at the outset of the pathfinder in September 2019, and then be revisited towards the end of the project to understand the reach and impact the pathfinder project and its interventions have had, and to make recommendations for future work and opportunities to develop the programme further.

iCASP hosting Exercise Augustus – surface water flood forecasting and response workshop

Introducing participants to the day’s activities and where the forecasts and data they will be seeing comes from

This week iCASP hosted a workshop for a range of organisations across Yorkshire involved with flood preparedness and response, and national organisations responsible for producing flood forecasts and alerts. The workshop was run to test out how useful it could be to combine probabilistic rainfall forecasts (Met Office Global and Regional Ensemble Prediction System, MOGREPS) with high-resolution hydrodynamic modelling (JBA’s JFlow®) to provide localised surface water flood forecasts.

A mock incident response situation – Exercise Augustus – was run using JBA’s Exercise Management System (JEMS), which presented representatives from Yorkshire’s Local Authorities, flood action group leaders, Environment Agency, emergency services and Yorkshire Water with the ‘new’ forecasts based on a real flooding incident in Leeds to see how they responded to the information they were given, and what decisions and actions they would take as a result.

Screen grabs of some of the information participants were shown during Exercise Augustus

This kind of incident response scenario planning gives us an understanding of the kinds of information that incident responders find most useful in helping them make their decisions – both in advance of an incident and also as the incident is unfolding.

Participants discussing the data and information and what it means ‘on the ground’, and what decisions and actions to take as a consequence

The participants worked in four groups so that their thoughts on the information they were presented with, and the rationale for their decision-making, could be understood and captured. A report will be produced summarising the different responses of the groups that will allow iCASP partners to better understand the ways to present information to flood responders, and which kinds of information elicit the most appropriate responses to the situation.

 

 

 

 

The flood that Exercise Augustus was modelled on took place in Garforth, Leeds on August 22 2015.

Enhanced Surface Water Flood Forecasting Project

Yorkshire is prone to all sources of inland flooding: from rivers, rising groundwater, flash floods and prolonged heavy rainfall which can cause surface water flooding. Arguably flooding from rivers is more straightforward to forecast because rises in water level can be measured and seen in advance. However, in the case of rainfall, it is harder to forecast precisely where heavy prolonged rain is going to fall and therefore if that rainfall will cause surface water flooding by landing somewhere with inadequate drainage.

Up until now surface water flood forecasts have been limited to relatively coarse–scale county-level red/amber/green warnings issued by the Flood Forecasting Centre and static risk maps, which are more useful for longer term planning. The iCASP Enhanced Surface Water Flood Forecasting Project will therefore convert the latest advances in probabilistic rainfall forecasting and high-resolution surface water modelling into useful real-time forecasts to help authorities which have to react to potential flood events.
