Influence of pit removal algorithms on surface runoff simulation

Sanja Šamanović, Damir Medak, Duška Kunštek

Abstract

The 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 without pits, involving minimum geomorphometric changes, is given based on geomorphometric and statistical analyses. The importance of selecting a correct algorithm is proven.
