D) divide average flow velocity by volume of flow

Question

Quizplus · Accepted Answer

Stream power is calculated by multiplying the shear stress exerted by flowing water on the channel bed and banks with the average velocity of the flow. So, the correct formula for stream power is given by Q x S [ρg(Sf+So)] where Q is discharge, S is the slope, ρ is the water density, g is acceleration due to gravity, Sf is the friction slope, and So is the bed slope.
