A Dual Porosity Lumped Parameter Model of Hillslope Hydrological Processes—A Case Study
The components of hydrological cycle remain more or less the same in almost all kinds of terrains. However, the redistribution of precipitation over hillslopes differs from that over moderate terrains in a number of ways. On hillslopes, non-horizontal water table and non-uniform soil saturation levels over the length of slope lead to simultaneous occurrence of infiltration and overland flow over different parts of the slope. Flow paths of a hillslope differ greatly in length, direction and response time, and the path taken by precipitation depends on the soil cover, the slope and the underlying geological setup. Moreover, the existence of preferential flow paths also modifies the hydrological response. In the present study, an attempt was carried out to model runoff generation processes on hillslopes. The model was applied to simulate the hydrology of Zabarwan hillslope, a part of the catchment of the Dal Lake in India. The model could successfully capture the physically observed hydrological phenomena in the study area.
