The invention relates to a method for determining the height of a spillway side wall, and aims at providing the method for determining the height of the spillway side wall so that the height of the side wall can be conveniently optimized and the waste phenomenon can be avoided. According to the technical scheme, the method for determining the height of a spillway side wall includes the steps that a, test water depth h data collection is conducted, wherein test data including the unit discharge under the free overflow state and the controlled overflow state and the test water depth h of the unit discharge of n engineering spillways are collected, and n is large than or equal to 6; b, the critical water depth hk is calculated according to the formula (please see the formula in the specification), wherein q represents the spillway discharge chute unit discharge with the unit of m<3>/(s m), alpha represents the kinetic energy correction coefficient, g represents the gravitational acceleration with the unit of m/s<2>; c, the relation of the test water depth h and the critical water depth hk is fit, wherein fitting analysis is conducted with the test water depth h in the step a and the critical water level hk in the step b as the foundation, and the function relation between h and hk is obtained; and d, the height of the spillway side wall is determined, wherein the height of the side wall meets the formula that H=h+K(hk-h), and K ranges from 0.3 to 1.0.
