Abstract: The paper is focused on the role of the soil water regime in formation of subsurface runoff. One-dimensional dual-permeability model is used to simulate variably saturated movement of water in the soil, in which preferential flow effects were reported. Simulated pressure head variations are compared with the available tensiometric observations. A possible conceptual model of prevailing water transfer mechanism in a hillslope segment is presented. The shallow subsurface flow is approximated by one-dimensional saturated flow along the inclined soil-bedrock interface. For a selected growing season, the model generated hillslope hydrograph is compared with the observed stream hydrograph. The simulated subsurface runoff peaks compare well with the measured stream discharge peaks.
