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...

Free crest spillways are hydraulically efficient and safe in operation. Since their discharge capacity is directly proportional to the crest length several types have been developed with the purpose to increase the length of the latter. Among these types traditional labyrinth weir spillways have been studied and used for a long time. Their hydraulic performance and the effect of the involved ge...

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...

throughout history dams have been important structures in water storage. to avoid overtopping, damage, and or failure of a dam, adequate spillway is needed to release excess water from upstream floods. researchers found that spillways have to be made nonlinear in order to reach an economic structure with high performance. a piano key weir is one of the best solutions. piano key weirs are the mo...

Additive Manufacturing (AM) offers a range of possibilities in fluid flow research. An existing 2.5 m open channel experiment contains set standard weirs which are limited design. This research will compare experimental AM (e.g. labyrinth, piano, catenary), that would not be possible on some laser-cut polymer or machined aluminium weirs. Due to the bespoke complex nature weirs’ design other man...

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...
