Numerical Study on Passing Flow Through Circular Channels with Side [PDF]
مهندسی منابع آب, 2017 Side weir is used as a slot in the side of main channel to direct excess flows that are above the weir crest. Such structures are used in control of flow level in irrigation, drainage networks and urban sewage disposal systems.

Discharge coefficient of side weirs in curved channels
Proceedings of the Institution of Civil Engineers - Water Management, 2012 Side weirs are flow diversion devices commonly used in irrigation, land drainage and urban sewage systems. It is essential for hydraulic and environmental engineers involved in the design of side weirs to predict the discharge coefficient correctly. The aim of this study is to present an accurate equation for discharge coefficients along the bend of ...

Flow characteristics at trapezoidal broad-crested side weir
Journal of Hydrology and Hydromechanics, 2015 Broad-crested side weirs have been the subject of numerous hydraulic studies; however, the flow field at the weir crest and in front of the weir in the approach channel still has not been fully described.

Three-dimensional numerical modeling of score hole in rectangular side weir with finite volume method [PDF]
Journal of Hydraulic Structures, 2017 Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design.

Evaluation of the Water Surface Profile over Semi Elliptical Side Weir [PDF]
مهندسی منابع آب, 2013 A side weir is a hydraulic structure with free flow, which is installed at one side and parallel to an open channel. It allows the water to overflow when the surface of the water in the channel rises above the weir crest. This structure affects the depth
