Webtwo weir options (rectangular weir or circular weir (orifice)). If rectangular weir is chosen, discharge through the weir is calculated as [9, 10] (19) (20) Where, Vflowout is the volume of water flowing out of the detention pond during the time step (m 3), dtp cdis is the discharge coefficient for the rectangular weir, dtp_totwrwid is 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].
