چکیده
Application geographic information systems (GISs) and remote sensing integration to provide determination of runoff from watershed has performed increasingly attention in recent years. In this study, Natural Resources Conservation Service Curve Number (NRCS-CN) method was used to estimate Curve number according to the factors of hydrological soil group, land use, land treatment, drainage basin characteristics, meteorological and hydrological parameters. The study was performed on the Kirazdere subbasin of the Yuvacık dam basin in north-west Turkey. Remotely sensed images from Landsat satellite was used to develop land use map of the study area. GIS analysis, based on land use and hydrological soil map data, was processed so as to determine spatially distributed runoff curve numbers on a 30-meter grid.

Investigation of Rainfall- Runoff Modelling of the Van Lake Catchment by Using Remote Sensing and Gis Integration
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 physica...
