Flow-path map for erosion risk
The flow-path map shows the new calculated flow paths for surface runoff (L-factor of the universal soil loss equation or of the erosion risk map) on the agriculturally productive areas within the field blocks. The flow paths are based on theSwissALTI3D terrain model and multiple-flow algorithms. They illustrate the areas where the topography would cause the water to collect and run off. The darker the colour, the greater the possible runoff levels, and hence also the erosion risk. This map does a good job of illustrating the erosion risk for linear erosion in slope depressions (thalweg erosion) and possible damage outside of the field block (off-site damage), e.g. on roads and in bodies of water.
