A labyrinth weir allows for higher discharge capacity than conventional linear weirs, especially at low hydraulic heads. In fact, this is an alternative the design or rehabilitation of spillways. It can even be used as a strategy in problems related to dam safety. sequential method based on optimal geometric parameters and results flow analysis using Computational Fluid Dynamics experimental st...

Abstract The compound labyrinth weir is a new type of that considered good applicable choice for increasing the capacity discharge. flow over complex problem because behavior three-dimensional. present study aims to simulate into critical regions cannot be observed when using an experimental test. computational fluid dynamics (CFD) programme was utilised implement sensitive analysis this purpos...

Abstract Side weirs are widely used in hydraulic engineering applications. The studies on the subject have been generally focused classical and labyrinth side weirs. However, same is not true for piano key (PKSW) a straight channel. weir (PKW) has high discharge capacity compared with In this study, characteristics of trapezoidal (TPKSW) channels were investigated experimentally. all experiment...

Recently, many research studies have focused on labyrinth weirs' hydraulic performance, especially as dependent engineering features. In the current study, properties of flow over triangular weirs models (from upper perspective) with sharp crest been experimentally studied and compare their efficiency suppressed rectangular (conventional weirs). Twelve fiberglass are developed for this reason t...

Abstract Labyrinth weirs are complex hydraulic structures. They have been widely used as a water regulator and to increase discharge in channels spillway dams. an economical effective method pass large floods. In addition, they reduce the requirements of structural footprint. These features make them interesting appropriate choice capacity discharge. Several factors affect performance labyrinth...

In this study, the effect of channel-bed slope and non-prismatic converging channel on discharge coefficient labyrinth weirs is numerically investigated utilizing FLOW-3D model. Numerical simulation results show that modifying weir through both methods improves coefficient. Among selected bed slopes wall, β=4% angle θ=10° yielded highest For a ratio HT/P=0.1, (HT: flow height, P: height) rate f...

Labyrinth weirs are utilized to transport a greater discharge during floods in contrast conventional due their increased weir crest length. Nevertheless, the geometric complexity of labyrinth weirs, determination accurate coefficients and accordingly, head-discharge ratings quite essential issues practical application. Hence, as first step present study proposes following eight standalone algor...
