Abstract
The configurations of debris-flow fan in a flooding plane were experimentally studied in the present paper. Experimental results show that the profiles of deposition depth of the debris-flow fan in a stable stage could be described by Gaussian curves both in the longitudinal and the transverse directions of the flow path. The shape of the fringe of debris-flow fan is similar to a half of an ellipse. The length, width and depth of a debris-flow fan in the stable stage have their own maximum values, Lc, Bm and Zo, respectively, for each case. The total volume V of a debris-flow fan could be simply related to these maximum values by V = α Lc Bm Zo. The shape parameter α was found to be 0.234 for sediments of uniform size. The dependence of α value on sediment size distributions was also studied.
