%X In order to explore the calculation methods of stilling basin depth and end sill height, we summarize previous research results about conjugate depth of hydraulic jump in trapezoidal stilling basin and measuring weir(sill)of trapezoidal cross section. According to energy equation, we present the calculation methods of stilling basin depth and sill height with trapezoidal cross section for 3 types of stilling basin, namely, deepened style, baffle wall style, and comprehensive style. On the basis of this, we put forward calculation formulas of stilling basin depth and sill height and exhibit the calculation process through examples. Finally, the calculation formulas can be taken as a reference for the design of trapezoidal stilling basins.
