Modeling discharge capacity of labyrinth weirs through a learning machine approach [PDF]

Journal of Applied Research in Water and Wastewater, 2019
In this paper, the discharge coefficient of weirs is simulated by the extreme learning machine (ELM). To this end, seven different ELM models are introduced by the input parameters.

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.

Investigation of discharge coefficient of trapezoidal labyrinth weirs using artificial neural networks and support vector machines

Applied Water Science, 2019
Weirs are a commonly used system to adjust water surface level and to control the flow in canals and hydraulic structures. Labyrinth weirs are a type of weirs that can pass through a certain amount of flow which has a lower upstream water level than the ...
