Flow over trapezoidal side weir

Flow Measurement and Instrumentation, 2011
Abstract In this paper, the hydraulic characteristics of a sharp crested trapezoidal side weir have been experimentally and theoretically investigated. It was found that the DeMarchi coefficient of discharge for a sharp crested trapezoidal side weir in subcritical flow is related to the main channel Froude number, the side slope of weir, ratio of ...

Determination of capacity of labyrinth side weir by CFD

Flow Measurement and Instrumentation, 2013
Abstract Side weirs are widely used in irrigation, land drainage, urban sewage systems, flood protection, and forebay pool of hydropower systems by flow diversion or intake devices. The hydraulic behavior of side weirs received considerable interest by many researchers.

Triangular Side Weirs

Journal of Irrigation and Drainage Engineering, 1987
Discharge characteristics of sharp and broad‐crested triangular side weirs have been experimentally investigated. Relations between discharge coefficient and main channel Froude number for different apex angles have been established.

Side-Weir Flow in Curved Channels

Journal of Irrigation and Drainage Engineering, 1998
Side-weirs located on straight channels have attracted considerable interest and research effort. The same, however, is not true for side-weirs on curved channels. The existing studies deal mainly with sediment transport problems and lateral intake structures.

Novel Approach for Side Weirs in Supercritical Flow

Journal of Irrigation and Drainage Engineering, 2013
AbstractSide weirs are hydraulic structures widely used in practice and extensively studied in the technical literature. The flow along a side weir is a classic example of spatially varied flow, the study of which is generally performed by means of a momentum or energy approach.

Side Weir in Rectangular Channel

Journal of the Hydraulics Division, 1979
The discharge characteristics of a side weir at the head of a branch channel taking off at right angles to the main channel have been investigated. Both sharp-crested and broad-crested weirs are studied for the case of subcritical flow in the main channel. A procedure of design based on De Marchi's theory has been evolved.

Minimizing the hydraulic side effects of weirs construction by using labyrinth weirs

Flow Measurement and Instrumentation, 2019
Abstract It is no doubt that weirs are one of the most important hydraulic structures that play a vital role in irrigation project. So, it is necessary to minimize the hydraulic side effects of weirs. Throughout this paper, experiments were conducted to investigate the suitable dimensions and shape of weir's crest to increase head loss, decrease ...

Computer Modeling of Side‐Flow Weirs

Journal of Irrigation and Drainage Engineering, 1993
A new computational procedure is presented that addresses the complex phenomena found in declining-flow regimes and does not require that the boundary conditions of the declining-flow segment be defined. These conditions are determined as a part of the solution of the larger problem of determining the flows in the entire conveyance system.

Determine the Length of the Side-Weir of Side-Weir Detention Basin Considering the Uncertainty of the Water Level in River

Journal of the Korean Water Resources Association, 2015
The existing flood protection in rivers has shown the limitation due to the urbanization around rivers and the abnormal climate. Thus, the demand for the constructions of side-weir detention basin are being increased as a part of integrated watershed flood protection plan.
