the density and velocity of debris flow is one of main contents of debris flow kinematics, and also basic parameter for prevention of debris flow. Based on studies on many calculation formulas of the density and velocity, a debris flow survey and test is carried on in Shishu. After study and analysis on data, a proper calculation formula is recommended. The density formula was verified, calculation result has good agreement with the test results; the calculation results of chosen Manning debris flow velocity formula have basically agreement with actual survey data, and the formula has comprehensive parameters, common significance and applicability. The recommended formula is appropriate for this area, and it provides geological basis for engineering design of debris flow prevention.
