An initial approach to the scientific management in the prevention of the debris flow

1,386 vallies with debris flows have been found since 1980s. In the period between the years of 1949 and 1985 more than 290 greater calamities in destruction of railway, deposition of the stations occurred. Among them were eight overturns of trains and two severe accidents with more than 100 casualties. And a catestrophy was occurred in every five deris flow gullies. The results of the cause analysis indicate that the current management is the weakest link in the prevention of the debris flow. It is advanced to establish scientific system of management, to sum up experiences in time, to standardize as early as possible, to carry out the policy of taking prevention as the leading work and to strengthen the construction of laws or regulations and implementation.
