Description:
Two methods, one using a travel time approach and the other based on optimization techniques, were developed to identify sediment generating areas within a watershed. Both methods rely on hydrograph and sedimentograph data collected at the mouth of the watershed. Data from several events were examined over two small watersheds, and a statistical procedure was utilized to assess the erosion vulnerability of different regions within the watersheds. Results from these two independent methods showed good agreement with USLE-based observations. These methods seem viable for practical use if the number of sediment generating regions is small, and good data from several events is available to achieve statistically meaningful results.
