Erosion rate of cohesive sediment has been investigated experimentally to understand the effect of some major factors, such as the clay content ratio, the water content ratio, a water temperature and etc., on the erosion rate. Based on the experimental results, a simple erosion rate formula was also developed. In the present study, several check tests were conducted to verify the validity of the previous results. Soil mechanical test was also conducted to evaluate the shear strength of the test sample. Correlation between the shear strength (cohesion) and an erosion rate was explained in the present paper.
