Abstract: Ephemeral gullies (EG) are localized areas of soil erosion that form from concentrated water flow in upland areas. Erosion from EGs in agricultural fields contributes a substantial fraction of annual upland sediment, and does so disproportionally (relative to other sources) during higher-flow events. Some general causes of EG erosion are known, however, mechanisms related to EG formation, location and geomorphological properties related to storm characteristics, and amount of soil lost are not understood well enough either to quantify the importance of EGs relative to other sediment sources in a watershed or to guide targeting of EG-effective best management practices (BMP). Therefore, the overall aim of this project is to gain a better understanding of the sources of sediment, quantify the sediment amounts, and evaluate the mitigation strategies to soil erosion contribution from ephemeral gullies on agricultural fields.
