Numerical Analysis of Free Flow over Rectangular Sharp-Crested Compound Weirs

Compound weirs are used as flow diversion structures by adding additional flow resistance to the anticipated regions at the rivers. Furthermore, they are used for measuring and regulating flow rates accurately over a wide range of flow depths. When they are used for this purpose, the cross sections are generally selected as symmetrical having...

Numerical modelling of flow over sharp-crested rectangular contracted weir

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...

A parametric method for submerged floating tunnel cross-section design

A submerged floating tunnel’s (SFT) cross-sectional geometry is one of the main factors influencing its hydrodynamic characteristics. Minimizing the drag and lift is important for reducing the displacement of the structure and load on the mooring system. In this study, a parametric cross-section design method based on the Bézier curve is used...
