Trapezoidal channels are frequently used in irrigation networks and other free surface water conveyance systems. The computation of the critical flow depth is one of the primary importance in the design process. It is usually determined by using design charts of iteration techniques. However, researchers have recently proposed formulas that directly provide approximate solutions. This paper presents an explicit equation for calculating critical flow depths in trapezoidal channels. The proposed equation is applicable to any trapezoidal channel dimensions and provides the highest accuracy among available methods.
