Under many circumstances, discharges from culverts and channels may cause erosion problems. To mitigate this erosion, discharge energy can be dissipated prior to release downstream. The purpose of this circular is to provide design procedures for energy dissipator designs for highway applications. The first six chapters of this circular provide general information that is used to support the remaining design chapters. Chapter 1 (this chapter) discusses the overall analysis framework that is recommended and provides a matrix of available dissipators and their constraints. Chapter 2 provides an overview of erosion hazards that exist at both inlets and outlets. Chapter 3 provides a more precise approach for analyzing outlet velocity than is found in HDS 5. Chapter 4 provides procedures for calculating the depth and velocity through transitions. Chapter 5 provides design procedures for calculating the size of scour holes at culvert outlets. Chapter 6 provides an overview of hydraulic jumps...

The purpose of this publication is to provide design information for analyzing and mitigating energy dissipation problems at culvert outlets and in open channels. It provides general information on the overall design process, erosion hazards, and culvert outlet velocity and velocity modification. These provide a background and framework for anticipating dissipation problems. In addition to describing the overall design process, design examples to compare selected energy dissipators are provided. Also provided are assessment tools for considering flow transitions, scour, and hydraulic jumps.

Recent advances in technology have permitted the construction of large dams, reservoirs and channels. This progress has necessitated the development of new design and construction techniques, particularly with the provision of adequate flood release facilities. Chutes and spillways are designed to spill large water discharges over a hydraulic struc

Stilling basins utili z ing a hydraulic jump for energy dissipation are w i d e l y used in hydraulic engineering . D a Vinci was the first to describe the hydraulic jump, and Bidone conducted classical experiments about 170 years ago . Stilling basins w e r e developed in the thirties with signif- cant design improvements being made during the last sixty years . Although w e l l - a c c e p t e d guidelines for a successful design are presently available, the information for the design of such dissipators is not yet compiled in book form . This book provides state-of-the-art information on hydraulic jumps and associat ed stilling basins . A large numbe r of papers on the to pics are reviewed. T h e present trends of the art of designing a stilli ng basin are discussed and ideas for future research are outlined. Design criteria and recommendat ions are frequently given . However, this should not be considered as a r eady-to -use guideline since the design of an effective stilling basin is much more comple x than following general design steps . The book is divided into two parts. Part 1 on hydraulic jumps is c- prised of chapters 2 to 5. Part 2 consisting of chapters 6 to 14 deals with various hydraulic structures used to dissipate energy. The lists of notation and references are provided in each part separately although the same notation is u sed throughout.
