This research concerns two projects: a hydraulic model study of the Calument Pumping Station, and a flow field study of the screen area and forebay of SEPA Station 3, both in the Chicago, Illinois area.

The flow patterns in the wet well and the suction conduit are modeled numerically to assess the hydraulic design of Calumet Pumping Station. The inlet discharge is 120 mgd (million gallons per day).

The flow field study for SEPA Station 3 was performed to identify the possible area where sedimentation could occur in the intake to the screw pumps.

2-D Modeling

This research concerns two different aspects of SEPA Station 3 in Chicago, Illinois. The first aspect was to develop a model that would check the flow structure in the intake area, identifying the possible reason which causes the deposition of solids onto the channel bed. The second aspect of SEPA Station 3 was to develop a model that would provide a general idea how the flow will change with the supposed redesign of the geometry in the weir area.
