Modeling Subsurface Hillslope Runoff Dominated by Preferential Flow: One- vs. Two-Dimensional Approximation

Original language description

Shallow saturated subsurface flow, frequently observed on hillslopes of headwater catchments in humid temperate climates, often dominates hydrologic responses of the catchments to major rainfall events. Typically, these responses are significantly affected by the presence of preferential flow. In this study, two approaches to modeling hillslope responses to rainstorms, which differ in dimensionality and thus also in the complexity of geometric, material, and boundary conditions, were tested and used onthe hillslope discharge data observed in an experimental trench. In the one-dimensional (1D) approach, 1D variably saturated vertical soil water flow is combined with 1D lateral saturated flow above the soil?bedrock interface. In this approach, verticalflow is modeled by means of a dual-continuum concept involving two coupled Richards? equations (representing flow in the soil matrix and in the preferential pathways), while lateral flow is described by the diffusion wave equation.
