The rectangular weirs with and without lateral contraction are theoretically examined, more particularly their discharge coefficient. Under the realistic assumption of a critical state at the location of the weir, the application of the energy equation be... see more

Rectangular short-crested weirs are widely used for simple structure and high discharge capacity. As one of the most important and influential factors of discharge capacity, side slope can improve the hydraulic characteristics of weirs at special conditio... see more

Due to its horizontal crest in the transverse direction and its inclined upstream and downstream faces, whose inclination is well defined, the Crump weir can be classified into the category of triangular longitudinal profile weirs, including the Bazin wei... see more

An in-depth theoretical and experimental study is carried out on a semi-modular device for measuring flow in open channels, in the current instance a rectangular open-channel of width B. The device is provided with both a crest height P and a lateral cont... see more

The article looked at the possibility of making use of a triangular broad crested device, provided with a crest height P and a constant apex angle q, as a flow measurement weir. The device has a triangular gorge which extends over a certain length L. This... see more

The study proposes a theoretical development in order to determine the relationship which governs the discharge coefficient of a contracted triangular weir. The theoretical approach takes into account the effect of the approach flow velocity which can be ... see more

The study deals with the thin-plate triangular notch weir as a flow measurement device. Unlike previous studies on this subject, a theoretical development is proposed which takes into account the effect of the approach flow velocity. Between two well-chos... see more

In this work, a numerical approach using finite element method is proposed for the integration of the nonlinear differential equation of the side weir flow in rectangular channel. After recalling the ordinary differential equation governing the problem, t... see more
