There are threefour figures below illustrating the “steady flow” HEC-RAS results. The first figure is a graphical output directly from HEC-RAS, showing the surface water profile of the modeled reach. The next twothree figures are comparing the surface water profiles developed by HEC-RAS and the STM calculation method. There is good agreement between HEC-RAS and the STM method, except for the M3 profile just downstream of the sluice gate. While HEC-RAS can model both subcritical and supercritical flows within the same reach, the did not produce an M3 Profile in this instance. <br /><br />
