V-Notch Weir Overflow: an Unsteady Calibration
Thin-plate V-notch weirs are commonly used as measuring devices in flumes and channels. Herein, the discharge calibration of a large 90o V-notch weir was performed using an unsteady volume per time technique. The weir overflow was initially shut. The sudden opening of the gate was associated with an initial phase of transient water motion associated with a negative wave propagating in the reser...
متن کاملScour Downstream Oblique V-notch Weir
Scour in bed material downstream weirs is considered the most unfavorable process which threats the overall stability of the weir. Weirs with oblique angle in the horizontal plan will affect the scour profile downstream the structure and may reduce it. The objective of this paper is to investigate the effect of oblique weir angle on the scour profile. Furthermore, the effect of V-notch angle on...

متن کاملdischarge computation of trapezoidal side weir in subcritical flow regime using conventional weir theory
introduction: side weir structures are extensively used in hydraulic engineering, irrigation and environmental engineering, and it usually consists of a main weir and a lateral channel. side weirs are also used as an emergency structure. this structure is installed on one side or both sides of the main channel to divert the flow from the main channel to the side channel. lateral outflow takes p...
متن کاملEvaluation of Seismic Performance of Weir Structures in Korea
Abstract—This study was conducted to evaluate the seismic performance of weir structures using two different approaches: i) design response spectrum with respect to KBC 2009 in Korea and ii) acceleration of time history (PGA, 0.3011 g) obtained from 1994 Northridge earthquake. This paper provided the simple linear elastic 2D plane strain FE model with the material nonlinearity including soil-fo...
