Abstract

The use of GIS and remote sensing to estimate basin runoff has increased in recent years. In this study, curve number and runoff maps of maximum rainfall of 6 hours with 2 year return period were required to map the height of the runoff. Runoff curve number maps were provided in the GIS environment with ARCCN-RUNOFF. Since runoff curve number is determined based on factors such as soil hydrology, land use, land cover, and hydrological conditions, ETM+images of 2002 in ERDAS software and supervised classification were used to develop the land cover map. In addition, the normalized difference vegetation index (NDVI) was used and accordingly pastures were categorized as good and medium, and forests as dense and mid dense. Maps of maximum rainfall of 6 hours were drawn based on the relations and equations of the raining basin by using the DEM map in the GIS environment. Integrating the obtained maps and the equations, the runoff height map was drawn. As a result, the average runoff was 3.18 mm which is more accurate than the findings of traditional methods (about 3.98 mm).
