No significant work has been reported on weirs fixed inclined to the flow surface or bed of the channel. The present work is a semi-theoretical and experimental analysis of flow over inclined sharp crested triangular weir, which is fixed inclined with respect to the flow surface or bed of ...
Over the previous decades, the flow over the traditional sharp-crested weirs was extensively investigated by many researchers; however, the well-escape weirs have not received sufficient attention. These types of weirs were mostly constructed in the form of vertical wells that may be circular or ...
For flow past a twodimensional sharpcrested weir located at the end of a horizontal rectangular channel, experimental results related to velocity and pressure distributions in the region of the nappe close to the weir crest section and the pressure distribution on the weir face were obtained. Based...

You can calculate the critical flow over a broad crested weir with the equation, Q = 1.6 L H^1.5. The broad crested weir is more robust than a sharp crested weir for use in natural open channels, like rivers and canals, where it is widely used for o

Rectangular weirs and triangular or v-notch weirs are often used in water supply, wastewater and sewage systems. They consist of a sharp edged plate with a rectangular, triangular or v-notch profile for the water flow. Broad-crested weirs can be observed in dam spillways where the broad edge...
Sharp crested weirs of different shapes have been developed over the years by several researchers. These weirs are being used for flow measurements by installing them as normal weir, oblique weir and side weir. In the present work, investigation is conducted on inclined weirs, having an ...
weirssteep slopesThe results of an experimental investigation on the characteristics of the combined flow over contracted sharp-crested rectangular weirs and below contracted sharp-crested rectangular gates are presented. The experiments are carried out in a laboratory flume using various geometrical ...
