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 In this study, changes in water quality characteristics were compared before and after the construction of eight multifunctional weirs Nakdong River Basin South Korea. A cluster analysis spatial variation showed that locations classified as Cluster 1 pre-construction (sites ND7 ND8) shifted into 2 post-construction, indicating types changed weirs. Principal component factor analyses re...

Poland is among the European countries with lowest water resources. The central part of features least resources in country. In this region, proper management particularly critical to maintaining high agricultural productivity. objective study was present effects restoration hydrotechnical infrastructure Rgilewka River catchment zone greatest deficits. This paper analyses such works on and thei...

Abstract Present study highlights the behavior of weir crest head and width parameter on discharge coefficient a compound broad crested (CBC) weir. Computational fluid dynamics model (CFD) is validated with laboratory experimental investigations. In analysis through weirs, upstream over (h) crucial, where result mainly dependent upon length (L) in transverse direction to flow, water depth from ...

Weirs are often constructed on mountainous rivers because of their low construction costs and ability to provide irrigation facilitate landscaping, yet there is little research how fish habitat quality in responds weir distribution. This study categorized the distribution characteristics weirs typical reaches according sinuosity calculated corresponding suitability index (HSI) weighted usable a...

The modeling of broad crested weirs is expected to facilitate understanding, especially the behavior flow flowing through measuring instrument. under consideration hydraulic behavior, measurement accuracy, and discharge curve. In addition, there a relationship between water level upstream downstream spillway, as well variation loss energy height. From results this study, it was found that upstr...
