A single strong meandering stream is often observed in double-row bars rivers which attacks river bank and causes local scouring and bank erosion in even medium-size flood.Therefore,to maintain the safety against flood in double-row bars,we need knowledge on mechanism of such formation process and factors which bring about a single strong meandering stream.In this study,a depth-averaged flow and bed-variation analysis is carried out under the regime condition in double-row bars.Results of the simulation show formation of a single strong meandering channel and bank erosion and invasion of excessive vegetation in bars are factors which strengthen such a single meandering stream.
