Determine the dynamic equation for the rate of change of depth having bed slope S0 and slope of total energy line Sf.

A. ( frac{dy}{dx} = frac{S_0-S_f}{1- frac{QT}{gA^2}} )
B. ( frac{dy}{dx} = frac{S_0-S_f}{1- frac{Q^2T}{gA^2}} )
C. ( frac{dy}{dx} = frac{S_0-S_f}{1- frac{Q^2T}{gA^3}} )
D. ( frac{dy}{dx} = frac{S_0-S_f}{1- frac{Q^2T}{gA}} )
Answer» D. ( frac{dy}{dx} = frac{S_0-S_f}{1- frac{Q^2T}{gA}} )
