N2 - The hydrological response of semiarid watersheds to rainfall events is
complex due to feedbacks between water fluxes, vegetation patches,
topography, and soil properties. This study investigates the combined
impact of rainfall intensity, infiltration contrast between bare and
vegetated areas, horizontal extension of the root zone beyond the canopy
size, slope steepness, and vegetation cover on surface hydrological
processes in a semiarid hillslope. Two modeling approaches are applied
to study the related rainfall-runoff relationships: a simple analytical
model and a two-dimensional numerical model coupling between surface
runoff and infiltration. Results indicate that the infiltration contrast
is the predominant factor allocating additional water to the local
vegetation.
