Abstract

The AA. present here a novel methodology CAFES (combined automated flood, elevation and stream power) to quantify downstream change in river flood power, based on integrating in a GIS framework "Flood Estimation Handbook" systems with the 5 m grid NEXTMap Britain digital elevation model derived from IFSAR (interferometric synthetic aperture radar). This provides a useful modelling platform to quantify at unprecedented resolution longitudinal distributions of flood discharge, elevation, floodplain slope and flood power at reach and basin scales. Longitudinal power trends are given for a sample of 5 river basins to demonstrate the usefulness of the approach. The CAFES methodology has significant international applicability for understanding basin-scale hydraulics, sediment transport, erosion and sedimentation processes and river basin management
