15 صفحه اولEffects of Digital Elevation Models (DEM) Spatial Resolution on Hydrological Simulation
Digital Elevation Model is one of the most important data for watershed modeling whit hydrological models that it has a significant impact on hydrological processes simulation. Several studies by the Soil and Water Assessment Tool (SWAT) as useful Tool have indicated that the simulation results of this model is very sensitive to the quality of topographic data. The aim of this study is evaluati...
متن کاملGeomorphometric Analysis of Maroon River by Digital Elevation Model
Digital Elevation Models (DEMs) are used to estimate different morphologies, analysis of river profile, delineating drainage basin and drainage pattern associated with lithological and structural changes. The study area is Maroon River located in Khuzestan Province, Iran. In this study geomorphometric analysis based on DEM carried out to understand Maroon river uplift rate and tectonic- erosion...
متن کاملQuality assessment digital elevation models
A number of published stereo matching algorithms have been implemented and tested on SPOT images of areas for which we have gridded digital elevation models (DEMs) available with spacings of 80m or less as well as ground control checkpoints. Results will be presented for a comparison of stereo matched output with the DEMs and an analysis of the errors arising and their causes. Results will be d...
