Assessments of dam spillways and hydraulic structures often consist of both physical and numerical modeling, with each approach complementing each other. One advantage of 3D CFD modeling is that you can gain detailed outputs from any cell within your model and are not hindered by data collection limitations that can be present in the laboratory or in the field. In this FLOW-3D HYDRO example, a longitudinal slice shows the velocity profile along the spillway. Of critical importance is to make sure the high velocity jet is directed upward and away from the streambed at the downstream lip of the energy dissipator, which is clear to see as the slice moves along the width of the spillway.
