Abstract

A partial sediment budget is developed from measurements of catchment sediment input, headcut recession and channel sediment discharge during 9 low-moderate size rainstorms for a gully headcut incised into the bare low angle alluvial Njemps Flats. Budget components vary with rainfall and slope conditions during individual storms, but the overall budget shows that approximately 50% of the sediment entering the gully head is derived from erosion at and around the headcut. The key factor in gully recession is high runoff discharge on barren smooth slopes. Preliminary results of grass seeding tests in the microcatchments are also presented
