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 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

The aim of this paper was the deduction of a new stage-discharge relationship for a contracted weir, having a crest length less than the channel width, by using the Malcherek’s outflow theory. The average outflow velocity over the rectangular contracted w... see more

This paper reports the computational fluid dynamics and experimental fluid dynamics studies conducted for the measurement of release by a composite broad-crested (CBC) weir. Studies conducted thus far depict that manufacturing composite weirs for precise ... 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

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

Manufacturing compound weirs for exact discharge measurement has been a challenge, according to studies so far. The length of the weir crest (L), weir height, and weir width all affect the efficacy of compound broad crested weirs as flow monitoring device... see more

A novel theoretical approach for the flow discharge relationship in a circular sharp crested weir is developed in the present paper. Based on the application of the energy equation applied between a section taken in the approach channel and the weir under... see more

The study is devoted to the parabolic-shaped thin-plate weir. It is the flow coefficient which is of particular interest to the study. This is planned to be determined from a theoretical point of view using the energy equation. This is applied between two... see more
