Description :
In this study, a high resolution digital elevation model (DEM) and detailed sediment particle sampling allowed a comparison of hillslope characteristics and particle sizes of surficial armoring in a semiarid watershed. Individual particle size classes on hillslopes are correlated with the underlying sediment type, local slope, aspect, and area draining through a grid element. These observations about process and spatial distrribution are useful in predicting the spatial distribution of particles on the watershed for applications such as distributed hydrologic models.
