Abstract
Weirs are flow control structures that can be used for flow diversion purposes. They are classified according to section geometry or their length in the flow direction. For sharp-crested rectangular weirs, Rehbock [1] derived stage-discharge equations. In contracted geometries, streamlines curve at the approach flow leading to variations in flow structures. For this case, [2] proposed an equation for discharge as a function of the opening rate at the section (ratio of opening width to total width, b/B). We developed CFD models to test their accuracy in modelling weir flow. For the contracted weir cases, flow structures were visualised upstream of the weir.
