Ephemeral gully (EG) erosion has been recognized as a major source of sediment in agricultural watersheds. Over the past few decades, soil erosion caused by sheet and rill erosion has been studied extensively, and field and watershed-scale models have been used to quantify contributions of sheet and rill erosion. In recent years, many studies have been conducted to understand EG formation, location and model development. The overall goal of this study was to develop a method to locate the potential EGs and further develop a simple model to estimate EG erosion at the watershed scale. To achieve this goal, several EGs were monitored, measured and overall characteristics described. Therefore, this paper focuses on monitoring and estimating sediment yields of few EGs in north eastern and south central Kansas.
