Box Canyon Dam
Pend Oreille Public Utility District contracted IIHR to provide hydraulic modeling and analysis to improve the design of fish passage structures for its hydroelectric dams, including Box Canyon.
Brownlee Dam
Idaho Power contracted IIHR to provide hydraulic modeling and analysis to improve the design of fish passage structures for its hydroelectric dams, including the Brownlee Dam.
Cardinal Power Plant
AEP sought IIHR's expertise to assess river hydraulics and complex flow patterns in the Ohio River near the Cardinal Power Plant. The project goal was to study the feasibility of installing submerged screens in the cooling water intake forebay to meet EPA requirements for fish impingement and entrainment.
Cowlitz Falls Dam Fish Collector
IIHR provided hydraulic modeling and analysis to improve the design of fish passage structures for many hydroelectric dams, including Priest Rapids on the Columbia River.
Hells Canyon Dam
IIHR constructed a large-scale physical model of the Hells Canyon Dam to test proposed fish-passage structures. This laboratory model complemented IIHR's advanced CFD capabilities to simulate performance of fish passage facilities.
McNary Dam
IIHR provided modeling and analysis to improve the design of fish passage structures for many hydroelectric dams, including Priest Rapids on the Columbia River.
Metropolitan St. Louis Sewer District
IIHR has extensive experience solving water issues, including the reduction of air in sewer systems. With Jacobs Engineering and the Metropolitan St. Louis Sewer District, IIHR constructed a physical model that includes a vortex dropshaft that, when constructed, will be one of the largest in the world at 20 feet in diameter.
Priest Rapids Dam
IIHR provided hydraulic modeling and analysis to improve the design of fish passage structures for many hydroelectric dams, including Priest Rapids on the Columbia River.
Pump Station 15 CFD Models
IIHR researchers worked with Pumping Station 15 in Madison Wisconsin as they retrofitted their pump to handle an increased capacity.
Self-Cleaning Culverts for Sedimentation Control
IIHR researchers have developed a culvert design that prevents blockage by sedimentation and vegetation. This self-cleaning system flushes out sediment deposits using the power of the stream flow itself.
Thames Tideway Tunnel
IIHR was a key partner in the massive effort to make London's sewer system fit for a world-class capital city—one of the largest wastewater infrastructure projects in the world.
Total Dissolved Gas Modeling
Total dissolved gas can be fatal for fish migrating through a hydropower tailrace and the river downstream. IIHR uses sophisticated computer simulations to develop strategies that will minimize TDG at hydropower dams and save fish.
Wanapum Dam
IIHR researchers have developed a culvert design that prevents blockage by sedimentation and vegetation. This self-cleaning system flushes out sediment deposits using the power of the stream flow itself.
Wave Energy Converters
The U.S. Department of Engergy (DOE) selected IIHR—Hydroscience & Engineering (IIHR), more than a thousand miles from any ocean, as a test facility for its prestigious Wave Energy Prize competition.
Wind Energy
IIHR research is working to better understand how weather conditions affect the performance of wind turbines — crucial information needed to build more accurate turbine flow models and optimize operation of turbines in less than ideal conditions.
