WebbDeriving runoff characteristics. Available with Spatial Analyst license. When delineating watersheds or defining stream networks, you proceed through a series of steps. Some steps are required, while others are optional depending on the characteristics of the input data. Flow across a surface will always be in the steepest downslope direction. WebbHEC-HMS software is used, and it showed that the runoff volume is 53% of the total rainfall depth, and the peak discharge is 132 m3/sec. This study provided an indication of the hydrograph characteristics and the result of this paper can be used for further flood studies in arid ungauged volcanic catchments.

WebbUse of remote sensing and GIS technology can be useful to overcome the problem in conventional methods for estimating runoff. In this paper, modified Soil Conservation System (SCS) CN method is used for runoff estimation that considers parameter like slope, vegetation cover, area of watershed.
