Branch selection for branching river is a common problem in inland channel construction,especially in large one,pros and cons of branch cannot be directly compared due to the huge investment,long-term effects on overall pattern of the reach and numerous factors involved.Taking the branch selection for 12.5 m-deep main channel in Fujiangsha Reach downstream the Yangtze River as an example,based on the analysis of the port adaptability,navigation risk,navigation interference,risk in construction and operation period,service level of waterway,anchorage convenience,investment and channel maintenance,we apply the CRITIC evaluation method to build the multi-target decision evaluation model.Based on the result of this model,we sort the branch selection options from good to bad,and validate the stability.The result shows that “Fuzhong one-way+ Fubei one-way” option is the best scheme for main deep-water channel in branch selection.
