Recent advances in technology have triggered a renewed interest in the stepped design, although much expertise had been lost in the past 80 years. The steps increase significantly the rate of energy dissipation taking place along the chute and reduce the size of the required downstream energy dissipation basin. Stepped cascades are used also in water treatment plants to enhance the air-water transfer of atmospheric gases and of volatile organic components (VOCs). This book presents recent progress in stepped chute hydraulics and provides a new understanding of stepped channel hydraulics. Results from more than forty five laboratory studies and four prototype investigations were re-analyzed and compared. Tags: hydraulics stepped chutes and spillways |
