Surface Water Impact Modelling (STA)

The aim of the project is to estimate the impacts on population, property and infrastructure of a realistic worst case scenario surface water flood event, using existing and up-to-date modelling and data. This would involve applying a 20-30% uplift to the rainfall inputs used in the London-centric South West scenario to produce a new, more extreme surface water scenario. The previously-developed hydraulic models would be re-run using these uplifted rainfall inputs and the outputs mapped/supplied as previously. Addi...
