This article presents the possibilities for implementation of the geomorphologic methods in estimation of the morphometric characteristics and relief dismemberment in flood hazard analysis for the Malki Iskar and Suha Reka river catchment above the town of Etropole. The results shown in the maps of the vertical and horizontal relief dismemberment in GIS exhibit a very high degree of conformity between the torrential river sections and the regions with high values of horizontal and/or vertical relief dismemberment.
