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 …

In this work experimental and numerical investigations were carried out to study the
influence of the geometric parameters of trapezoidal–triangular labyrinth weirs (TTLW) on …

A spillway with Trapezoidal Labyrinth Shaped steps (TLS) is proposed and investigated
numerically. The results show that this spillway has better performance as it increases the …

In this paper, the effectiveness of airfoil-shaped pier with and without a collar on local scour
depth reduction is numerically investigated utilizing FLOW-3D model. The results show that …

Labyrinth weirs increase the discharge rate by increasing the effective length of the weir
within a confined width. In this paper, an attempt was made to improve the hydraulic …

In this study, the effect of the presence of bed-block roughness in an ogee spillway on
energy dissipation and jet length is investigated. A series of experimental and numerical …

The creation of an opening in a broad-crested weir body increases the discharge coefficient
and reduces the water elevation behind the weir. In this study, three-dimensional numerical …

Side weirs are utilized to regulate water surface and to control discharge and water
elevation in rivers and channels. Here, the discharge coefficient for trapezoidal sharp …

This work presents numerical simulations carried out to study the influence of geometric
characteristics of pooled steps on the energy dissipation performance, flow patterns …

Dealing with kinetic energy is one of the most important problems in hydraulic structures,
and this energy can damage downstream structures. This study aims to study energy …
