Book Description
Stepped channel design has been in use for more than 3,500 years. Recent advances in technology have triggered a regained interest in stepped design, although much expertise has been lost in the last 80 years. The steps significantly increase the rate of energy dissipation taking place along the chute and reduce the size of the required downstream energy dissipation basin. Stepped cascades are also used in water treatment plants to enhance the air-water transfer of atmospheric gases (e.g. oxygen, nitrogen) and of volatile organic components (VOC). Results from more than forty-five laboratory studies and four prototype investigations were re-analysed and compared. The book provides a new understanding of stepped channel hydraulics, and is aimed both at researchers and professionals.

Book Description
This section of the National Engineering Handbook describes the chute spillway. Chute spillways are defined as open channels with steep slopes, in which flow has supercritical velocities. They usually consist of an inlet, vertical curve section, channel, and outlet. The major part of the drop in water surface takes place in the channel. Flow passes through the inlet and passed down a paved, steeply sloped channel to the floor of the outlet. Various designs and proportions are in use. Further research and systematic evaluations of experience with existing structures will lead to continued improvement in design and proportions. However, confidence can be placed in the design principles contained herein, for they are conservative when available information does not permit them to be stated precisely.
