Experiment for determination of soil erosion rate under the effect of overflow

Abstract

    Erosion on the surface of the dam under the effect of the flow is the primary cause of the development of dam break. Study of soil erosion mechanism under the effect of overflow is necessary to evaluate dam safety when overtopping dam . Previous researches have established the formula for calculating soil erosion rate. However, it is necessary to do experiment to determine the erosion coefficients in the formula in each different types of land. This paper presents the content of an experiment to determine soil erosion rate on hydraulic glass trough, and using this result to identify the erosion coefficients of land .
