Abstract
The simplified calculation methods for the submergence coefficient and the sill height of sill-type stilling basin are researched to substitute the traditional trial method. On the basis of previous researches, the iterative formula of submergence coefficient is derived through optimizing fitting, and the simplified calculation method of the sill height is analyzed. Furthermore, the drag coefficient of the sill is researched through momentum equation to provide technical support for its intensity design. The fitting and iterative formula of submergence coefficient, the simplified formula of sill height and the formula of drag coefficient are put forward and verified correct by examples. The iterative and simplified formulas are simple in form, and avoid the complexity of trial method.
