Abstract:

The report contains a first order analysis of the supercritical flow in an overfall based on the use of the stream line function as the basic dependent variable. It presents approximate equations for the nappes, and a formula for f 1, epsilon which is a good approximation to the brink depth ratio ba for the range 0 or epsilon or 1. Author
