The calibration of sharp-crested weirs with a horizontal edge used for measuring flows in partially full pipes [PDF]
Journal of Water and Land DevelopmentThis paper presents the results of a laboratory study on the discharge capacity of sharp-crested weirs fitted with a horizontal edge in pipes during open-channel flow conditions and clean water used to measure the outflow.

GeogacetaThe study of fracturing at Ain Bouchermou, Ain Maârouf, and Ain Boujaoui water sources used satellite image analysis, isobase analysis, and structural field study to reveal new data on hydrological flows and water storage in karsts and breccias. Mapping the fracture network identified three groups of oriented fractures: N-S, NESW, and NW-SE, with the ...

Experiment on Free Overfall Measuring Flume in Rectangle Canal
工程科学与技术, 2015 :In open channels, free overfall is a situation where the flow separates from the rigid bed to form a free nappe due to a sudden drop in the channel bed, the relationship of the end-depth to the critical depth is constant, it could be used as a simple ...

پژوهشهای زیرساختهای عمرانی, 2020 One of the major challenges in dam engineering is the design of the discharge flow of the stepped spillway. The rate of energy dissipation in downstream currents is higher than that of skimming currents. To achieve this goal, the discharge and skimming slope of the spillway must be low, which makes it economically efficient and applicable.

Demystifying the discharge coefficient for flow over thin weirs and sills
FlowA revised derivation of the discharge coefficient for flows over thin weirs and sills in the limits of wall overflow to a free overfall is given. Using dimensional analysis, we show that the discharge coefficient, $C_{d}$ , in the classical weir ...
