Abstract

Based on second order analysis of observed rainfall a cluster point rainfall model is identified for each month. Hydrograph analysis provides information about the characteristics of the hydrologic response during flood events. Model based analysis of hydrologic response is used to study the dominating runoff processes in the catchment. A distributed version of Topmodel is used to model runoff generation. The runoff generation model relies on a topographic index to predict saturation excess runoff and on Philip's infiltration equation to predict infiltration excess runoff. The relative roles of initial conditions, soil properties, and rainfall rate in determining hydrologic response in the basin are investigated. The flood frequency distribution seems to be quite insensitive to scaled maximum rainfall intensity. However the flood frequency distribution is very much affected by the scaled initial storage capacity. -from Authors
