Use of the discharge-weighted average velocity in studies of the frictional energy loss of streamflow

Authors(s) and Affiliation(s)



Existing resistance equations are designed, and have been historically used, to estimate discharge from manufactured conduits and streambeds which resemble them. They produce a value for the area-weighted average velocity, which can then be multiplied by the cross-sectional area to produce an estimate of discharge. In more recent times, researchers have also begun to study energy loss, a use for which the area-weighted average is inappropriate. The discharge-weighted average velocity of streamflow is proposed as an alternative. More generalized resistance equations may assist in evaluating the range of channel conditions in the natural world
