The Role of Hillslope Hollows in Generating River Discharge.
Abstract
This investigation sought to undertake an analysis of soil water movement on shallow, undulating topography with the specific aim of isolating the spatial and temporal nature of hillslope zones contributing preferentially to streamflow in such topography. With the combined used of data on soil water potentials from the study site and a simulation program designed to replicate soil water movement processes on hillslopes, it was shown that only in relatively restrictive cases of topography/soil/stream gradient configurations, does soil water convergence always take place into hillslope hollows. The implications of this finding in the context of static indices, hitherto used to identify those hillslope zones that saturate preferentially, is discussed. It is further shown that relatively minor variations within the shallow topography area studied are capable of enducing significant differences in the hillslope outflow hydrographs.
