Method of improving flow conditions of ship navigation at end of central bar of branched channel

The invention discloses a method of improving the flow conditions of the ship navigation at the tail of the central bar of a branched channel, belongs to the field of channel improvement, waterway regulation, and hydraulic structure application, is mainly used for improving the flow conditions of the ship navigation at the end of the central bar of the branched channel, then ensures that a ship smoothly enters and exits the navigable branched channel, and reduces the probability of occurrence of maritime traffic accidents. The main technology comprises the following steps of: step (1). arranging a substantial longitudinal dike at the end of the central bar; step (2). arranging a flow guide mound at the end of the central bar; step (3). jointly arranging the longitudinal dike and the flow guide mound at the end of the central bar; and step (4). arranging a transparent longitudinal dike at the end of the central bar. Compared with the prior art, the method can provide a feasible hydraulic structure and a specif
