Abstract
When performing engineering surveys, it is recommended to calculate the discharge and values of 1% and 5% of the debris-flows frequency. This frequency is calculated as 1% and 5% flow frequency of water discharge and flood water levels. Such calculations, in turn, are performed on the basis of calculations of 1% and 5% of the precipitation frequency falling. However, the debris-flows frequency does not always correspond to the water flow frequency. This is because the dominant role of the debris-flows process is played by geological factors of debris-flows formation. The occurrence of a debris-flow is preceded by a period of preparation of loose-rocks in debris-flows site (accumulation of a critical volume of loose-rocks and its achievement of a certain degree of moisture of loose-rocks) and the flood that caused the formation of a debris-flows in its parameters may be less than the flood. Equal in repeatability to with the correspond...
