Comprehensive review on Water Energy Dissipation by using Hydraulic Jump

Abstract

This research paper looks at how energy dissipation is important for hydraulic structures, especially spillways, to reduce local scour and prevent structural failures. It examines traditional and new techniques for energy dissipation by formation of hydraulic jump, focusing on the most used appurtenances in stilling basins. Comprehensive review addresses how gravitational potential energy turns into kinetic energy, which affects shear stress and sediment transport. It details different methodologies for energy dissipation, the role of the Froude number, standardized designs from the U. S. Bureau of Reclamation, Type I, II, III and IV and enhancements such as baffle blocks, end sill and baffled chutes. Experimental results validate these designs to improve hydraulic performance and manage costs effectively.
