Confined and mined: anthropogenic river modification as a driver of flood risk change

This repository contains inuput data (i.e. polygons, numeric data, HECRAS files) used for two-dimensional HECRAS hydraulic modelling to estimate patterns of flood inundation and shear stress. Files are also for the use in Geomorphic Chnage Detection software.  

All geospatial data is in WGS 1984 UTM Zone 51N.
