"WebFree-Surface Modeling Flow over a broad-crested weir is a typical air-water two-phase ﬂow. To capture the free surface at the interface between the water and the air, the InterFoam solver in OpenFOAM is used in the present study. This solver is based on the volume-of-ﬂuid (VOF) method developed by Hirt and Nichols [28]. " - Inclined rectangular weir-flow modeling
