摘要:The aim of this study is to determine runoff depth of the Van Lake basin by using remote sensing and geographic information system (GIS) integration. While determining the results we used various data sets such as Landsat satellite image, 1:25000 standard topographic map, and soil map data. Standard 1:25000 topographic maps were used to derive digital elevation model. Sub-basin area and physical characteristics of the study area such as slope and aspect maps were determined with the help of DEM into GIS as layers. Digital Elevation Model was used to determine basin model through Hec-GeoHMS . Landsat image was classified by using digital image techniques and integrated into GIS with hydrological soil map. Soil Conservation Curve Number method was used to determine curve numbers and runoff depth distribution of the basin area. We show that remote sensing and GIS technology are suitable for analysis of the runoff depth distribution of the basin area. The proposed method can be applied to predict for ungaged watersheds, flood, and other water resource applications
