Abstract

The smallest volume of the blocking of Dadu River by the debris flow at Moxi River is 842,600 cubic meters according to the calculations of the total source and the minimum size of the blocking. In the total source of the debris flow at different frequencies, when P equals 2 % (50-year of recurrence), the total source of Moxi River is 830,000 m3, so it is quite possible to have a blocking incident.
