Collaborating with the Environment Agency to deliver flood risk modelling and mapping

Following severe flooding in East Anglia, we were tasked to collate and transform recorded data into useable datasets, that would demonstrate the extent and impact of the flooding.


We worked with the EA’s Partnership and Strategic Overview (PSO) team to deliver new and updated flood risk modelling and mapping as identified in the East Anglian Area Annual Plan.


Incident data collation and Recorded Flood Outline (RFO) production
The RFO highlighted elements of data that could add value to other tasks in the project work flow.

Level, threshold and topographic surveys
Around 400 properties were surveyed combining a mixture of properties that flooded from the river, and properties outside the area.

Model and flood warning updates
We used data from the event and ran it through the Mid Ouse model package. The model results were compared to the RFO and commentary was provided to discuss the model performance.


This project progressed to update key mapping datasets such as the RFO, Flood Warning and Alert Areas and also improved the existing modelling capability for key main river watercourses.

The outputs of this study will be used for a number of key flood risk management activities such as flood risk mapping, flood warnings, and benefit/damages assessments to inform capital investment decisions and maintenance, and to plan the EA’s incident response.
