Long term operation of rivers can easily lead to sedimentation due to frequent erosion,which raises the water level and may exacerbate flood disasters,posing a threat to the safety of the river.Therefore,in order to avoid the risk of leakage and landslides during the flood season of the river,it is necessary to carry out river management projects based on the actual situation of the river.Based on the current situation and engineering overview of a certain river engineering project,the paper designs the river course control projects such as the retreat culvert project and the retreat lock project through detailed hydraulic calculation.After the implementation of the project,it can effectively improve the flood discharge capacity of the treated river course,improve the coastal water ecological environment,and enhance the overall environmental quality.
