LXGB: a machine learning algorithm for estimating the discharge coefficient of pseudo-cosine labyrinth weir [PDF]
Scientific Reports, 2023 One of the practical and financial solutions to increase the efficiency of weirs is to modify the geometry of the plan and increase the length of the weir to a specific width. This increases the discharge coefficient (C d ) of the weir.

The energy dissipation of flow over the labyrinth weirs
Alexandria Engineering Journal, 2022 In this study, the energy dissipation of flow over the triangular and trapezoidal labyrinth weirs with one and two key cycles was investigated. The magnification ratios (MR) of models were 1.57, 2.57, 3.57, and 4.57.

Investigating a new approach to enhance the discharge capacity of labyrinth weirs
Journal of Hydroinformatics, 2023 Climate change has caused the inefficient operation of a significant number of old weirs to pass large discharges. Therefore, this study aims to increase the discharge capacity of the labyrinth weir.

The effect of the energy head and the inlet and outlet key width on discharge coefficient of Piano key weir [PDF]
فناوریهای پیشرفته در بهرهوری آب, 2023 IntroductionPiano key weir is a form of nonlinear weir designed to improve the discharge capacity of spillway structures. Due to the increase in effective length, they can be used in dam spillways or water regulation structures.

Experimental and Numerical Study of the Discharge Coefficient in Parabolic Labyrinth Weirs [PDF]
محیط زیست و مهندسی آب, 2021 An increase in the hydraulic capacity of flow conveyance over a weir per a given stage of a stream upstream of the weir is feasible by extending the effective length of the crest of the weir per unit width of flow section. In this work, in order to study

Determination of Discharge Coefficient for both Semicircular and Triangular Labyrinth Weirs
Polytechnic Journal, 2021 A Labyrinth weir is a type of nonlinear weir folded in plan-view, with the ability to pass a large flow at low heads due to an increase in the effective length of the weir crest for a given channel width.
