A Study of pressure fluctuation caused by hydraulic jump in stilling basin [PDF]
مهندسی منابع آب, 2018 A stilling basin is one of the energy dissipaters downstream of a spillway. The place of maximum pressure caused by jet impact and the effect of various factors on the amount and location of pressure are important factors in designing of stilling basin ...

Three dimensional flow simulation over a sharp-crested V-Notch weir
, 2020 Thin-plate weirs are widely used to monitor the flow rate in open channels. Thereby, three dimensional (3D) modeling of the flow over a weir in an open channel can be considered as one of the main topics in hydraulic science. In this study, the flow over

Experimental investigation on sharp crested rectangular weirs
, 2020 Sharp crested rectangular weirs used for discharge measurement purposes in open channel hydraulics are investigated experimentally. A series of experiments were conducted by measuring discharge and head over the weir for different weir heights for full width weir. It is seen that after a certain weir height, head and discharge relation does not change.
