Improving forecasting for surface water flooding

With much of the map of England lit up with flood warnings and alerts this morning, this serves as a timely reminder about the importance of ongoing work into flood forecasting.

The recent iCASP project on Enhanced Surface Water Flood Forecasts (ESWFF) set out to try to enhance the forecasts that are issued to help decision making in the run up to, and during, a flood event. A wide range of people utilise these flood forecasts including the emergency services, flood planners in local authorities, water utilities and the Environment Agency.

The culmination of iCASP’s ESWFF project was a mock incident response workshop in April that used data from a previous flood incident to see if enhanced forecasts would lead to different decision making. Involving many different flood responders in the workshop gave useful insight into the value placed on different kinds of information, how decision makers use different pieces of information and how the information could be further improved for clarity and ease of use.

Several recommendations came out of the project, including how to better support local authorities in their responses to surface water flooding, and further development and testing of user-centric surface water forecast information.
