Calculate flow direction and flow accumulation In theDerive Continuous Flowalgorithm, there are two basic steps in the least-cost path approach applied to flow routing. First, valid outlets are set. Valid outlets are cells where water can flow into but not outwards. By default, outlet cells ...
The floods thus occur because of the outflow of the surface water body. In large catchments, long-lasting precipitation evenly distributed in time and space leads to pronounced flooding. However, especially in small catchments with an area of around 100 km2, heavy rainfall events can also lead...
