WebStandard step method. The standard step method (STM) is a computational technique utilized to estimate one-dimensional surface water profiles in open channels with gradually varied flow under steady state conditions. It uses a combination of the energy, momentum, and continuity equations to determine water depth with a given a friction slope ... WebOne formula that particularly intrigued me was Eq. 15-1 in Chow's book. This equation states that the efficiency of the hydraulic jump, i.e., the ratio of the specific energy after the jump to that before the jump, is equal to: E 2 /E 1 = [ (8F 12 + 1) 3/2 - 4 F 12 + 1] / [8F 12 (2 + F 12 )] The proof of this formula is particularly challenging.
