Description :
The aim of this paper is to identify dominant erosion processes as the surface condition is changed through a series of laboratory rainfall simulations on a dual-box system. Variables changed are slope steepness, seepage and drainage, and rainfall intensity. These data sets are used to evaluate the conceptual framework for sediment detachment, deposition and transport processes, especially on the role of sediment transport capacity. A trial run was also conducted to isolate seepage effects on sediment delivery from the increased runoff due to the background seepage flow.
