Runoff Generation in Shallow Hillslope Soils at Watersheds with Different Forest Cover

Popis výsledku v původním jazyce

Our study focuses on runoff generation for a shallow hillslope soil and on the possible impact of the type of vegetation covering the watershed. Flow in a hillslope soil is modeled as superposition of two components: one-dimensional vertical flow in twocommunicating flow domains: the soil matrix domain and the preferential flow domain, and one-dimensional downhill saturated flow along the impervious or less permeable soil-bedrock interface. The S1D DUAL code is applied to the observed data to simulatevertical flow. Subsequently, a model solving one-dimensional Boussinesq equation is used for simulating shallow saturated subsurface flow. To evaluate the process of runoff generation, simulated fluxes at the boundaries are compared with the observed specific discharge rates. The shallow subsurface runoff seems to be one of the dominating processes which determine the response of the studied upland watersheds to intense rainfall.
