In this study, a series of laboratory tests were performed to investigate the effects side ramp slope, crest length, and porous media properties on flow regimes, water-surface profiles, discharge coefficients, energy dissipation in embankment gabion weirs with upstream downstream slopes. 24 physical models solid three different upstream/downstream slopes (90°, 45° 26.5°) created. To complexity ...

While there are a wide range of design recommendations for using rock vanes and bendway weirs as streambank protection measures, no comprehensive, standard approach is currently available engineers to evaluate their hydraulic performance before construction. This study investigates 2D numerical modeling an option predicting the vane weir structure designs protection. We used Sedimentation River...

the rectangular broad crested weirs are widely used to measure the water dischargewhich is one of the most popular tools in the irrigation canals particularly, in developingcountries.the present article is trying to demonstrate the results of an experimental work carriedout on rectangular broad crested weir with sloped upstream face to investigate the effect ofupstream slope on discharge effici...
