Abstract	A PHYSICALLY -BASED STUDY OF THE MECHANISM OF SEDIMENT DETACHMENT IN THE SOIL EROSION PROCESS This study presents a critical evaluation of the mechanism of detachment in an erosion process. Sediment detachment is defined as the dislodgment of soil particles from the soil mass during an erosion event. The dislodgment is caused by the forces applied by both overland flow and raindrops. The detachment of sediments is also dependent on a number of other factors, especially on those that are affecting the soil erodibility. The first part of this study comprises a comprehensive literature review of the general area of sediment detachment. The literature review includes the examination of the current methods of quantifying the rate of sediment detachment and the identification of the areas that require further development. The general conclusion from this review is that there is a need for the development of a more detailed theoretical and engineering-based equation for predicting the rate of sediment detachment and for assessing soil erodibility in order to provide an improved physically-based erosion model. The second part of this study consists of the development of a new equation to describe the mechanism of sediment detachment in the erosion process. The equation is based on the concept that soil particles will be detached from the parent material if there is a net upward force greater than zero acting on the particles. The forces acting on the soil particles include those from the erosive agents (overland flow and raindrops), seepage, self weight and cohesion. The primary advantage of this equation is that it helps change the basis of prediction of the rate of sediment detachment from empiricism to the utilization of physically based variables. Therefore, it is possible to separately
