Interpretive Summary: This study was designed to better understand the basic physics of soil erosion by water. The objective was to determine how various factors such as energy and forces associated with flowing water cause soil particles to become detached. We measured the flow depth, velocity, slope, and quantity, and along with these factors we also measured the amount of soil eroded. The results showed that flow energy and flow velocity appear to be the critical factors that determine the rates of soil detachment by flow. These results will provide scientists information to build better technologies for assessing erosion rates, which in turn will help land managers make better decisions to help conserve America's soils. The impact will be an improved soil resource base for the country necessary for sustainable food production into the future.
