Many of the problems experienced with water supply intake structures on western rivers result from a failure to mitigate the effects of moving sediments. Shallow but varying flow depths further complicate intake design. Difficulties can range from a moving channel bed burying an intake structure to excessive suspended sediment intake creating major solids handling and equipment problems. This paper presents theory and application of intake design principles related to maximizing the intake of water and minimizing the intake of sediment, floatables and aquatic life. Illustrations are taken from intake structures designed by the authors on the South Platte and Colorado Rivers.
