Shi Yuan - Soil Erosion and GeoWEPP

Shi Yuan (Stephen) is interested in Urban Hydrology and optimal deployment of water resources in urban areas. At UWA he is working with Ben Marillier. Stephen's project, titled "Validation of GeoWEPP in Western Australian Landscapes" uses data gathered from two catchments in WA to test the WEPP (Water Erosion Prediction Project) model for validity in the Western Australian landscape. The two catchments represent a high-rainfall area and a low-rainfall area. The catchments are located in the Chapman Valley region near Geraldton. Spatial data gathered (topographic, soil, climatic and land-use) will be analyzed using GeoWEPP to estimate hillslope erosion and sediment yield for small sub-catchments. Modelling results will be assessed in the field to examine suitability of the model for erosion hazard mapping.
