Overview
Horner & Shifrin designed a 130 million gallon per day raw water intake, including a 65 ft by 50 ft by 63 ft deep reinforced concrete structure in the Missouri River, divided into three pump cells. As part of the design effort, two physical models were constructed and run by the Iowa Institute of Hydraulic Research; one 1:5 scale model of the pump cell for hydraulic tuning, and one 1:20 scale model of the entire structure to design vanes to control sediment buildup.
