For urban rivers, in addition to meeting the requirements of normal flood discharge, a certain landscape effect must also be achieved. Therefore, there are forms such as broken line weirs, maze weirs, and arch dams. However, the existing overflow weirs only make changes to the line structure, thereby changing the water flow state and improving the landscape coefficient, and have no water purification and ecological improvement functions.
