OPTIMAL HYDRAULIC CONDITION OF DEBRIS FLOW DRAINAGE CANAL
You Yong · 1999
The optimal hydraulic conditions of triangle cross_section and compound triangle cross_section were presented. The results show that the optimal hydraulic condition of debris flow drainage canal is that the ratio β of width b to depth h is 2 for triangle cross_section and β=1+m 2-1 for compound triangle cross_section. The hydraulic condition of different types (trapezoid, rectangluar, triangle and compound triangle) of debris flow drainage canal have been discussed. The conclusion of this study is of reference value for the disaster control and prevention.
