In addition, flow conditions below different fishway types have been examined, and velocity distributions at weirs with V-shaped crests in both pool-and-weir fishways and at a single weir have been compared in different discharges and drops. Fishway flows have been compared with flows over ...
Side weirs are extensively used in the hydraulic and environmental engineering applications. The modeling of free surface flow over a labyrinth side weir i... MC Aydin - 《Advances in Engineering Software》 被引量: 55发表: 2012年 Experimental observation of flow characteristics over a Piano Key ...
Flow over Gabion Weirs Hassan I. Mohamed 1 Abstract: A conventional weir typically consists of an impermeable body constructed of concrete, since its primary functions are to heading up water and efficiently regulate flow. However, an impermeable body prevents the longitudinal movement of aquati...

Broad crested weirs are widely used for flow measurement and regulation of water depth in rivers, canals and other natural open channels. Broad crested weir flow rate calculations can be made with a rather simple equation if the weir height is great enough to cause critic...
EXPERIMENTAL INVESTIGATION OF COMBINED FLOW OVERWEIRS AND BELOW GATES Weirs and gates are frequently used as measuring devices because a simple stage-discharge relationship can be deduced. Weir and gate system is a plate that... M Heydari,MM Ahmadi,M Rahimpour 被引量: 0发表: 2012年 Description...
However, in the numerical model, the 4m weir was replaced with two side weirs with the length of 2m which were placed within two meters distance from each other. The primary contributions of the paper are to show that a numerical model can be used to simulate the flow over both single ...
