Abstract
By taking bending shoal-cutting of Water Conservancy park in Lingjiang as a case, the change of flow pattern in the curved channel before and after the shoal-cutting project is analyzed by numerical simulation, and application effect is analyzed. By analyzing the tidal level data of the engineering reach, the appropriate barrier clearance elevation is determined. The relationship between water level variation and different range of shoal-cutting is established, and the suitable range of shoal-cutting is recommended. It has an important reference for the management of bend in tidal river.
