Modeling of rainfall-runoff and soil erosion processes in various scales and using various DEM ? assessment of effects
Original language description
Rainfall-runoff, erosion and transport processes are of high importance within an area of interest and are often modeled by computer tools of different mathematical approach and precision. Each model requires different set of input data and provides different possibilities to simulate surface runoff pattern complexity. In case of distributed rainfall-runoff models digital elevation model is the essential input. This paper presents results of sensitivity study on DEM?s source and resolution for two fullydistributed model tools. The simulations were carried out using empirically based continuous model WATEM/SEDEM and physically based event model Erosion 3D. The elevation data used were: (i) 10x10 m resolution DEM GEODIS (professionally treated commercially available raster DEM), (ii) 5x5 m resolution DEM derived from contour-lines in original scale 1:10000 with equidistance 2 m and (iii) 3x3 m resolution DEM derived from laser-scan elevation LiDAR 5G data. The goal of the modeling was t
