Deducing the weir flow stage-discharge relationship is a classical hydraulic problem. In this
regard Buckingham's theorem of dimensional analysis can be used to find simple and …

Inclined rectangular weirs, also named pivot weirs, are used both to adjust the upstream
water level and to increase the flow capacity compared with that of normal rectangular weirs …

In this study, an integrated measurement and control facility with an airfoil weir as the
primary overcurrent structure is proposed by considering the flow characteristics over …

Pivot weirs have been proved efficient to measure, control and stabilize open channel flows
in an easy-to-use manner. This work presents a numerical investigation of free surface …

A pivot weir is a measuring and regulating structure that benefits fixed weirs and can be
used to set the level of water from long distances in modern irrigation networks utilizing a …

An inclined rectangular overflow structure, also called a pivot weir, consists of a rectangular
plate, angled downstream from the vertical, that can be used as an upstream water level …

A large collection of laboratory measurements of piezometric head (h) and discharge (Q)
were made over hydraulic models of a tilting weir at nine different angles, ranging from 25.7° …

Pivot weirs have a lifting mechanism to change the weir angle relative to the channel bed.
These are installed across the waterways in the form of multiple weirs in a row. The water …

Overshot gates are used as a flow measuring device to fix the upstream water level. Flow
through the overshot gates under submerged conditions often has many problems, mainly …

The aim of this paper was the deduction of a new stage-discharge relationship for a
contracted weir, having a crest length less than the channel width, by using the Malcherek's …
