Hydraulic and Environmental Aspects of Long Crested Weirs
نویسنده
چکیده
Long crested weirs are gaining popularity amongst the hydraulic engineers owing to obvious hydraulic advantage of flow magnification. These weirs can pass much higher floods from the available width of a natural water course. Such weirs may also be introduced in water treatment plants for mixing of chemicals. This paper discusses the advantages of long crested weirs, such as duckbill and labyrinth weirs. An account of hydraulic as well as environmental aspects such as discharge relationship, weir aeration, thermal stratification, fish migration, vegetation response and downstream scouring associated with long crested weirs has been presented herein.

CFD SIMULATION OF FLOW OVER CONTRACTED COMPOUND ARCHED RECTANGULAR SHARP CRESTED WEIRS
Measurement of discharge in open channels is one of the main concerns in hydraulic engineering. The structures used for this aim should be accurate, economical and easy to use. Weirs are among the oldest and most convenient hydraulic structures that have been used in both laboratory and field for flow measurement in open channels. Due to limitations of simple sharp crested weirs, recently compo...

متن کاملEffect of Height of Sharp-Crested Weir on Discharge Coefficient
Weirs have widely been used for the flow measurement, flow diversion and its control in the open channels. Attempts have been made to study flow over different shapes of normal weirs, side weirs and oblique weirs. This paper is connected with the development of the discharge coefficient measurement. In the present study four different weirs in different height are considered for validation purp...

Truncated sharp crested weirs are used to measure flow rate and control upstream water surface in irrigation canals and laboratory flumes. The main advantages of such weirs are ease of construction and capability of measuring a wide range of flows with sufficient accuracy. Artificial neural networks (ANNs) and genetic programming (GP) have recently been used for estimation of hydraulic data. In...
