Facilities

The Utah Water Research Laboratory's (UWRL) modern, comprehensive hydraulic flow facilities are located on the Logan River, a clean freshwater source capable of delivering 230 cfs to laboratory facilities. With over 50,000 square feet of research space, the UWRL offers a variety of flumes, channels, pumps, pipelines, equipment, and instrumentation for conducting hydraulic research, model studies, valve testing, and flow meter calibrations.

Water is supplied by gravity flow from an upstream reservoir through a 48-inch diameter pipe to the laboratory. The reservoir supplies a constant pressure head of 25 feet to the main laboratory level and 35 feet to the lower laboratory level. A network of steel piping (18, 24 and 36 inches in diameter) located under the floor supplies water to various parts of the lab. Other under floor channels conduct water from the experiments back to the river, to re-circulating pumps, or to precise flow measurement facilities.

Laboratory research is supported by a wood and machine shop that houses necessary stationary and hand tools for physical model construction, custom steel and acrylic fabrication, and heavy equipment maintenance. The laboratory includes forklifts, a mobile crane, and skid-loaders to aid in the construction of experiments.

Other features of the hydraulics laboratory include a 400 square-foot rainfall simulator and a sunlight simulator integrated with a tilt-able, soil-filled test flume. These simulators enable students and faculty to conduct a wide range of studies related to erosion, runoff, infiltration and crop production.
