In this research, Remote Sensing (RS) and Geographic Information System (GIS) techniqueswere used for runoff potential estimation in Khosro-Abad watershed, located in the Hamedan region.In this regard, first, the various thematic maps layers such as Digital Elevation Model (DEM), landuse and land cover, slope, soil hydrologic groups and sub-basins location were prepared. Then, basedon the prepared thematic layers, a weighting method was developed to runoff potential estimation ofthe area. To spatial runoff variability investigating, the classifieds estimated runoff potential (low,medium, high and extreme classes) was evaluated using the SCS method. The SCS method wasestimated based on three previous soil moisture conditions (dry, normal and wet). The results showedthat the weighting method is enable to runoff potential estimation. This method can be proposed forrunoff potential estimation especially in the cases that the needed data were missed. The results alsoshowed that with the previous soil moisture increasing (from dry to wet conditions), the CN increaseabout 30%. %U https://jise.scu.ac.ir/article_13275_1e2268b41f3e7675a66946fa466a2ce1.pdf
