This paper presents a new two-dimensional finite-volume numerical model to study the adjusting effect of the Anqing river waterway regulation,covering three continuous bending braided channels,i.e.Anqing,Taiziji and Guichi Waterway. A series of prototype observed hydrologic data are adopted to verify the model’s parameters.The computed water level,splitting ratio,and cross section velocities of the model agree well with the measured values,which indicate that the model may be used to model the flow processes in Anqing channel.
