Physical hydraulic model tests were conducted to investigate the hydraulic characteristics of a selected formed suction intake (FSI) design subjected to various hydraulic conditions. A variety of pump bay lengths and widths were evaluated. Hydraulic performance was evaluated by measuring flow distribution, swirl angle, and vortex intensity. Test results revealed that the FSI provided satisfactory flow to the pump with adverse flow in the approach. Test results are presented in dimensionless terms in plots and sketches. (JG).
