Velocity distribution and discharge calculation at a sharp-crested weir

Paddy and Water Environment, 2013
A sharp-crested weir in open channel is a useful device to calculate discharge via head-discharge relationship. However, water stage measurement site and discharge coefficient significantly influence discharge calculation accuracy. Therefore, this study measures and simulates velocity distribution at the weir section using 16-MHz MicroADV and FLOW-3D ...

GEP Modeling of Penetration Depth in Sharp Crested Weirs

Arabian Journal for Science and Engineering, 2011
Aeration in the waters of rivers and streams is very important to the existence and quality of aquatic life. Aeration is the process by which the area of contact between water and air is increased, either by natural methods or by mechanical devices. Contact time between water and air is also very important. Increasing the contact time of air bubbles is

Flow over Sharp-Crested Trapezoidal Planform Weirs

2017
The most common structure for discharge measurement in streams is a weir. Generally, they are used as normal weirs which allow water to pass gradually over their crest, causing submergence due to afflux at upstream. For passing more discharge with low head, the weirs of different planforms were recommended to improve their discharge capability with ...
