Hydraulic jump in a rectangular channel, also known as classical jump, is a natural phenomenon that occurs whenever flow changes from supercritical to subcritical flow. In this transition, the water surface rises abruptly, surface rollers are formed, intense mixing occurs, air is entrained, and often a large amount of energy is dissipated.
A polynomial weir is a weir that has a geometry defined by a polynomial equation of any order n. [11] In practice, most weirs are low-order polynomial weirs. The standard rectangular weir is, for example, a polynomial weir of order zero. The triangular (V-notch) and trapezoidal weirs are of order one. High-order polynomial weirs are providing ...
Cipolletti (Spanish pronunciation: or [tʃipoˈleti]) is a city in north of the Patagonian province of Río Negro, Argentina. With a population of 105 482 inhabitants at the 2022 census [ INDEC ] , Cipolletti is the third-most populated settlement in the province, after San Carlos de Bariloche and General Roca .
Roller dams are a type of weir, or a dam that is designed to allow water to flow over the top in continuous action. They are used on rivers or other such moving bodies of water where erosion damage is undesirable, yet likely to occur.
A drop structure, also known as a grade control, sill, or weir, is a manmade structure, typically small and built on minor streams, or as part of a dam's spillway, to pass water to a lower elevation while controlling the energy and velocity of the water as it passes over.
In hydraulic engineering, a nappe is a sheet or curtain of water that flows over a weir or dam. The upper and lower water surface have well-defined characteristics that are created by the crest of a dam or weir. [1] Both structures have different features that characterize how a nappe might flow through or over impervious concrete structures. [2]
The Neuquén-Cipolletti bridges are a series of four bridges that connect the cities of Neuquén and Cipolletti by spanning the Neuquén River, in Argentina. Three parallel ones, two road bridges and a railway bridge, were built on a former herd wrangling path.
Tilting Weir Animated Schematic. In order to operate, the tilting weir needs to be manually or mechanically opened and closed. Small tilting weirs are operated with hand wheels and electric motors but other methods have been employed especially for larger structures. Tilting weirs are usually controlled by human intervention but a self ...
