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.
