Influence of pit removal algorithms on surface runoff simulation
Abstract:Influence of pit removal algorithms on surface runoff simulationThe digital terrain model (DTM) with removed pits is a precondition for hydrologic analysis. Two pit removal methods, the carving method and the filling method, are investigated in the paper for three different geomorphometric areas. The input data are digital elevation models (DEM) created by interpolation from photogrammetric surveying in the spatial resolution of 5x5 meters. A recommendation for the use of a more acceptable DEM creation method … Show more
