Abstract

This paper describes the preliminary application of a spatially-distributed method to quantify patterns and rates of sediment production in the Xihanshui basin, a tributary of the upper Yangtze; and to predict its routing to a downstream point, accounting for losses in deposition. This is based on a use of SedNet, a distributed model in which the component processes are represented by reduced complexity sub-models to facilitate application at large spatial scales. The purpose of this paper is therefore to assess the relative importance of sediment production processes under different climate and land cover conditions, and the controls of the spatial structure of delivery ratios within this large catchment, rather than to make explicit forecasts of sediment production and yield for practical purposes
