Abstract

This study has investigated Natural Flood Management (NFM) in a tiered approach across the Eden, Kent and Derwent catchments in Cumbria, to help prioritise where different NFM measures are likely to be more effective. Commencing with a rapid overland flow modelling approach using a 2m
resolution 2d inundation model (JFLOW), a screening was undertaken to identify where modification of features in the landscape to slow and store surface water flows might make the most difference. These included Runoff Attenuation Features (RAFs), tree- planting, and soil structure improvements. Following a stakeholder workshop with catchment partners, these opportunities were refined and sub-catchments were prioritised for more detailed modelling using Dynamic TOPMODEL. The JFLOW models were re-run, and the benefits were re-computed and summarised in a suite of interactive maps that can be used, along with a User Guide, to help inform decisions at the wider catchment scale.
