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...
In this study, the discharge coefficient of side weirs located on converging channels was simulated for the first time using a new method of Extreme Learning Machine (ELM). To examine the accuracy of the numerical model, the Monte Carlo simulations were used and the experimental values validation was conducted by the k-fold cross validation method. Then, the input parameters were detected for s...
خTo reduce the construction costs of stilling basins of hydraulic jump type is sometimes, novel geometries are sometimes used to adopt the basin to the upstream and downstream sections without any transition structures. Otherwise, any changes in the geometry of the basin would cause changes in the conditions and characteristics of the hydraulic jump. In this study, the effects of variation in b...

Abstract In this research, the models of Inflatable weirs with internal pressures 0.5 and 1.4 at three heights 0.15, 0.2 0.25 m were constructed. The deflectors used in two geometric sections, including rectangular triangular shapes, they installed angles 30, 45, 60 degrees downstream weir body. results showed that value Cd changes between 0.28 0.35 while range ratio upstream flow head on crest...
in the present study, experimental investigations about the hydrodynamics of the conical cap tray (concap tray) have been carried out. the concap tray is an innovative and novel type of cap trays. the effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the concap tray was measured, compared and correlated. the hydraulic experiments w...
