Abstract: Normal depth is an important parameter in open channel analysis and has ramifications for flood prediction. Calculation of normal depth can be done by various methods but there is no simple analytical solution. All of the existing methods either have a complex chain of equations or are iterative. A regression equation is presented here that is computationally more efficient than the existing methods and introduces little additional error.
