The Environment Agency (EA) has published a new research report that will help flood risk managers identify and manage the uncertainty in their flood risk assessments and flood defence designs.
This new guide is written for all flood risk management authorities, developers, and engineering consultants who work on their behalf. The EA and Natural Resource Wales (NRW) are now currently exploring how to adopt this research in their work.
Current (June 2017) advice on the use of this guide is:
EA/NRW capital projects underway should not revise their cases to account for this new guide
New capital projects can either continue using W187, or can join our pilot studies to trial the new approaches in the research report (see below)
Developers should submit flood risk assessments to EA/NRW in accordance with local advice until advised to do otherwise
A webinar recording from March 2017 that details the research behind the guidance can be viewed here.
The EA and NRW are developing a programme of pilots with front runner operational areas teams to test the new methods. Candidate area pilots are currently being identified and resource for this work will be agreed. This work will be led as a partnership between EA and NRW. It will be delivered by representatives from national Asset Performance and Engineering Teams with support from both Planning and Regulation and Modelling and Forecasting Teams.
If you are involved in a new capital project and would like to be involved in our pilot studies, please contact email@example.com.
