Introduction Intake and Outfall Structures basin

The IOS or Intake and Outfall Structures basin is a facility for scale model testing of pump sumps and other intake and outfall structures to improve the flow. These structures are used for intake and discharge of water and can be found in systems for cooling water, desalination, sewage water treatment and irrigation.
Two separate multifunctional basins are available for scale model testing of pump sumps and other intake and outfall structures. Scale models still provide the best and most detailed answers to optimise these large civil constructions from a hydraulic point of view and to ensure a trouble free operation.
The Deltares IOS (Intake and Outfall Structures) basins 1 and 2 are available for model testing of almost any kind of hydraulic structure. The large IOS-1 basin has an area of 20×12.5 m2, and allows for cross flow in order to model (cross) channels or rivers. The smaller IOS-2 basin has an area of 6×16 m2 and allows higher water levels. In this way, smaller designs can be studied on a larger scale.
