Abstract

Based on data from 107 Chinese alluvial rivers, a study has been made to relate river channel patterns to the water discharge ratio (ζ) index. These rivers can be classified as four channel patterns, i. e., braided, low concentration meandering, hyperconcentration meandering and island. It was found that, when mean annual water discharge (Q) is given, the ζ index for hyperconcentration meandering rivers is the highest, for braided rivers the second, for low-concentration meandering rivers the third, and for island rivers the lowest. A discriminating model has been proposed for the above four channel patterns, based on the relationship between ζ and Q. Three threshold lines between the four channel patterns are well identified. Of the 107 Chinese rivers studied, 84.7% are correctly predicted using the proposed model
