Empirical relationships derived from erosion plot data are incorporated into a GIS framework to predict soil loss in the Middle Hills, Nepal. The region experiences high natural rates of soil loss exacerbated by the expansion of terraced agriculture and thinning of forests. Estimates of erosion are undertaken for individual rainfall events and quantify soil loss on a grid cell basis throughout a whole catchment. Material detached on the hillslope is subsequently routed towards the channel network using flow direction data in conjunction with a simple runoff velocity equation. The GIS framework enables the impact of land use and climatic change upon erosion to be assessed. The potential for using data derived from satellite imagery in erosion studies is explored; simple image processing techniques have discriminated the broad land-use types of the Middle Hills region and broad variations in soil erodibility can potentially be determined using imagery recorded in the dry season.
