Description :
The AA. present an application that delineates river networks and catchment boundaries across the European continent from a medium resolution (250 m) digital elevation model (DEM). They exploit novel algorithms based on the concepts of mathematical morphology and implement a landscape stratification drainage density. The result has been validated by comparing the derived data to digital river and catchment data from other sources and with varying scales of observation.
