NEW OPTIMIZED EQUATIONS WITH INTELLIGENT MODELS FOR PREDICTING HYDRAULIC JUMP CHARACTERISTICS OVER ARTIFICIAL AND NATURAL ROUGH BEDS
The available studies for estimating the characteristics of hydraulic jump are only for artificial or natural beds, and very limited researches have simultaneously considered artificial and natural beds. The aim of this study is to present comprehensive equations and models for predicting the characteristics of hydraulic jump in artificial and natural rough beds with various dimensions, arrange...
متن کاملInvestigation of Undular Hydraulic Jump over Smooth Beds
Undular hydraulic jumps are illustrated by a smooth rise of the free surface followed by a train of stationary waves. They are sometimes experienced in natural waterways and rivers. The characteristics of undular hydraulic jumps are studied here. The height, amplitude and the main characteristics of undular jump is depended on the upstream Froude number and aspect ratio. The experiments were do...
متن کاملAnn Model for Prediction of Length of Hydraulic Jump on Rough Beds
Hydraulic jumps have immense practical utility in hydraulic engineering and allied fields, such as energy dissipater to dissipate the excess energy of flowing water downstream of hydraulic structures (spillways and sluice gates), efficient operation of flow measurement flumes, chlorinating of wastewater, aeration of streams which are polluted by biodegradable wastes and many other cases. The le...
متن کاملHydraulic Jump over Negative Slopes with Negative Steps
Many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. On sloping basins, however, few such studies have been performed so that the issue requires more investigation. A significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. This study was carried ...
