determining affected areas using a model to predict landslide prone areas (SHALSTAB) combined with an empirical model designed to …: (a) elaboration of a digital elevation model (DEM), (b) application of the deterministic SHALSTAB model to locate the … landslide prone areas, (c) identification of the debris flow travel distance and area of deposition, and (d) mapping of the …

This paper presents a GIS-aided procedure for shallow landslide susceptibility mapping at a regional scale. Most of the … slope geometry, have been derived from the digital elevation model (DEM) while vegetation cover and thickness of superficial … susceptibilityassessment is very sensitive to the parameters selected. Compared to thetraditional methods, the main advantage of the GIS …

A GIS-based method has been applied for the determination of soil erosion and sediment yield in a small watershed in … catchment outlet is represented by the topographical characteristics of the cells. The effect of DEM resolution on sediment … yield is analyzed using two different resolutions of DEM. The spatial discretization of the catchment and derivation of the …

large areas there is a strong need for effective and objective landslide hazard assessment at a regional scale. In … large areas. Against this background the goal is the development of a satellite remote sensing and GIS-based system for … Upper Maili Suu river basin a methodological framework has been developed incorporating remote sensing and GIS techniques …

Grid based digital elevation models (DEM) are commonly used in water resources modeling. The quality of readily … available DEM, however, varies from source to source in terms of horizontal resolution and vertical accuracy which are the two … important aspects of elevation uncertainty in the modeling with raster GIS. This paper addresses the issue of elevation data …

in the region under study using the technique of GIS-based remotely sensed image that give us more accurate results and … less time consuming to process data comparing with the GIS-based Topographic Maps (GTMs). This modern technique provides …
