8.2 Utah Water Research Laboratol'Y Experiments

The Utah Water Research Laboratory, located at Utah State University in Logan, Utah is a
50,000 square-foot facility containing 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 up to rates exceeding
200cfs 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-the-floor
channels conduct water from the experiments back to the river, to re-circu1ating 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 uses 2 forklifts,
a mobile crane, and 2 skid-loaders to aid in the construction of experiments.

Also contained within the hydraulics laboratory is a 400 square-foot rainfall simulator, and a
sunlight simulator integrated with a tiltabJle soil-filled test flume. These facilities enable
students and faculty to conduct a wide range of studies related to erosion, runoff, infiltration,
and crop production.

In summary, the hydraulics laboratory at lhe Utah Water Research Laboratory contains the
following:

NIST Traceable Flow Measurement Equipment
. 1000-lb weigh tank
. 30,000-lb weigh tank
