Waterway regulation countermeasures of Baimaosha waterway in the lower reach of the Yangtze River

According to the navigation problem and through riverbed evolution,mathematical model and physical model,etc.,we analyzed the rule of riverbed evolution and evolution trend,and carried out an in-depth research on the countermeasures of waterway regulation.The general ideas on the waterway regulation and regulation scheme were recommended to guarantee the existing favorable river regime and waterway pattern,and lay a foundation for the implementation of the follow-up regulation engineering.
