Abstract In this research, the models of Inflatable weirs with internal pressures 0.5 and 1.4 at three heights 0.15, 0.2 0.25 m were constructed. The deflectors used in two geometric sections, including rectangular triangular shapes, they installed angles 30, 45, 60 degrees downstream weir body. results showed that value Cd changes between 0.28 0.35 while range ratio upstream flow head on crest...

Side weirs as flow diversion devices are usually used as emergency weirs in large hydraulic structures like dams and irrigation and drainage networks, because of their importance they require delicate design. As a result application of numerical and simulation models play an important role in design of these hydraulic structures. In this research, the flow pattern and shear stress distribution ...

Side weir is a type of weirs that used extensively in a variety ofengineering projects such as river engineering, dam,waste water , Irrigation and drainage network. So the study on the flow characteristics on the type weir, is one of the mostimportant topics in hydraulic engineering. The spatially varied flow (S.V.F)with discharge decreasing is governing equation to this type weir.Study on the ...
