It tells particularly the debris flow"s the encironment and the development characteristic by numbers . And according to its character , selecting the latest research results at present , the anthor calculates the debris flow"s the moving , dynamical characteristics and the scale , such as , the velocity of flow , the wallop , the peak value flux , and the total flux . And the anthor calculates density in different design frequency by the empirical formula method . In the text, the author uses the modle of evaluating a single gully to evaluate the risk of the debris flow . First , the author calculates the hazard degree in different design frequency , and forecasts the risk range of debris flow in Shenjia gully based on the maximum pile thickness and the total solid amount of a denbris flow . Then , on the basis of the risk range in different design frequency , the author carries out the damageability and risk assessment . The basic purpose of risk management is reducing risk or transferring risk , reducing the loss of life and property . The text constructs the system of risk management of debris flow in Shenjia gully , basis on the condition of Shenjia gully .
