Data for: A novel and enhanced calibration of the tilting weir as a flow measurement structure

To achieve reliable and equitable water distribution it is necessary to
accurately estimate the volumetric discharge of water flow through rivers
and canals. One such method of accomplishing this is by using hydraulic
structures, such as the tilting weir. This structure not only can be used
to measure the discharge of water on a continuous basis, but also allows
for regulating the water level upstream of the structure. Presently,
tilting weirs are often used to control water levels, but the literature
on their utilization as flow measurement structures has remained sparse.
This study presents a thorough analysis of laboratory experiments on
scaled models of tilting weirs, where the flow depth upstream of the
structure (i.e., head) and the inclination angle are used to calibrate an
equation to estimate the discharge to a high degree of accuracy.
Operational guidelines to ensure minimum uncertainty in measurement are
also given. The data published here include head and discharge
measurements for all experiments conducted, including information on the
experimental location, date, and model dimensions. Publication of this
data is intended to allow other researchers to verify the calibration
procedure laid out in the primary article, and as a comparative dataset
for future calibrations.
