Abstract: The Jeffrey Energy Center draws its cooling water make-up from the Kansas River near Belvue, Kansas. At this site, the Kansas River is a shallow sand-bed river of constantly changing bottom geometry. A design for a water intake that is capable of maintaining intake capacity at all river stages is presented. The intake design is environmentally acceptable and requires minimum maintenance. Two modifications to the existing river conditions were made. A jetty was constructed across the meander to direct low flows to the screen structure. During normal flows most of the jetty is submerged. The second modification was an upstream revetment constructed against the bends outer bank. The revetment stops bank sloughing and directs the river flow towards the intake.
