  • Weirs and flumes – Mine Closure

    IntroductionDescription of The MethodAppropriate ApplicationsPerformanceDesign Requirements and InstallationReferencesVnotched weirVnotch weirs have triangular shaped crosssection, where the angle of the Vnotch varies The most common values of the angle are 90° and 45°, but smaller angles are used for very small flows, and bigger, eg 120° angle weirs for higher flow rates (Shaw et al 2011) Once the weir has been installed HflumesThe design of the Hflume uses features from both weirs and flumes It has a triangular crest, but in inclined position towards the upstream Additionally, instead of being a damlike structure under the crest opening, such as in weirs, Hflumes have flat bottom and they are unobstructed throughout the whole dParshall flumeParshall flume is open along the whole depth of the structure and consists of three separate sections The first section upstream constricts the flow to a short and narrow throat section, from where the flow continues to a uniformly diverging downstream section The upstream section is the longest one with flaMeer bekijken op mineclosuregtkfi
  • What is a Weir? — Practical Engineering

    09032019  A weir is a small dam built across a river to control the upstream water level Weirs have been used for ages to control the flow of water in streams, rivers, and other water bodies Unlike large dams which create reservoirs, the goal of building a weir across a river isn’t to create storage, but only to gain some control over the water level
