IIHR’s 10 facilities include several large warehouse-sized buildings designed specifically to accommodate large physical models. Physical hydraulic modeling is a core strength at IIHR, perfected through decades of experience developing innovative designs and supporting applied hydraulic research. With IIHR’s demonstrated expertise, experience, facilities, and equipment, we can build a precision model of any hydraulic structure.
James Street Laboratory (JSL), purchased in 2003, provides large open space for river models. The building’s capabilities include large overhead doors and high ceilings for greater flexibility and easy access, and 300 Hp of pumping capability for ground recirculating models.
Most of the space in the Model Annex is available for a constantly changing array of short-term small- and medium-sized hydraulic models for both applied and fundamental research projects. These models are continuously being built, utilized, and torn down here.
Hydraulics Annexes One and Two offer space for large models, including fish passage studies and stormwater conveyance structures. HA1 has a 75,000-gallon sump pit for water storage. HA2 features 24-foot-high clear-span construction and large overhead doors, so very large models can be built and tested without interference from roof support columns. HA2 is also home to IIHR’s new wind tunnel, constructed in 2014.
