"WebStream discharge – total volume of water in the stream. It is a function of the cross-sectional area of the stream (width and depth), and the velocity. A wide, deep stream will have a greater discharge than a shallow, narrow stream, assuming their flow velocity is the same (Michaud 1991, p. 29). Reference: Michaud, Joy P. 1991.
