Abstract
Rill development has long been recognized as a key process in hillslope erosional response, usually linked to rapid increase in rates of sediment delivery. Rill systems have also been viewed as important components in drainage basin evolution, following the pioneer work of Horton and Schumm. Many research projects have addressed the critical threshold conditions involved in rill initiation, but most have focussed on individual rills. Few studies have addressed rills as components of networks of frequently complex geometry, or the influence of this geometry on water and sediment fluxes. Most rill research has been carried out on disturbed agricultural soils. It is not clear that the results can be easily extrapolated to natural hillslopes on less disturbed soils where subsurface flow and micropiping are frequently of much greater significance. This paper discusses these issues in the context of recent field and laboratory research, and reevaluates the role and significance of rill development in hillslope evolution.
