In this article FLOW3D Computational model have been used to calculate water flow profile over a rectangular broaded crest weir and in Gharnave check dam in north east of Iran moreover its designed USBR stilling basin capability to damp energy is investigated and finally two different modifications in its stilling basin is proposed and analyzed. Numerical output shows that this commercial software can predict flow profile and hydraulic jump in this hydraulic structure in general
