Comparison of Two Different Approaches to Modeling Subsurface Runoff at the Hillslope Scale
Original language description
Two conceptually different approaches to numerical modeling of a hillslope response to a rainstorm are presented and compared. In the first approach, the flow of water in a variably saturated hillslope segment is described as vertical planar flow using two-dimensional Richards' equation. Preferential flow effects are taken into account by formulating a dual set of two-dimensional governing equations, which reflects the dual character of the flow in the soil matrix and in the preferential flow domain. Inthe second approach, one-dimensional variably saturated vertical flow is coupled with one-dimensional saturated subsurface flow along the soil-bedrock interface. The saturated downhill flow is described by one-dimensional diffusion wave equation while the vertical flow is modeled using a dual set of one-dimensional Richards' equations.
