Abstract

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
