Experimental study on the interior slope of scour pit below debris flow sabo dams
2009
Study on the interior slope of the scour pit below the debris flow sabo dam can provide foundation to estimate the erosion range,the dimension,the shape and the development of the longitudinal profiles.According to the flume experiments,the upper slope in the scour pit is much steeper than the lower,and it changes with the flume angles and composition of silt on the bed.For the same grain composition,the slope in the scour pit with cohesive silt is much steeper than that with non-cohesive silt.Baced on experimental data,the quantitative relationships among the interior slopes,the rest angle of the silt under water and the initial angle of flume were established by regression analysis.
