Environmental and hydraulics laboratory


The Environmental and Hydraulics Laboratory is a shared-use facility supporting our research and teaching missions. Its primary features include:

  • Research laboratory for environmental engineering
  • Experimental equipment for hydraulics engineering
  • Lecture and presentation space with seating for 36 students

The research laboratory is equipped for studies on (1) water, wastewater and environmental remediation; (2) alternative energy generation from microbial fuel cells and biofuels; and (3) stormwater-related research, including infiltration tests through engineered base materials, clogging measurements for life-cycle analysis, and (4) calibration studies for street Type 14 and 16 inlet capacities, study of Types C and D inlets for highway drainage design, support of on-campus mini weather station, and field tests on stormwater detention system. Key analytical instruments include an anaerobic chamber, a gas chromatograph, and a high-pressure liquid chromatograph.

Our teaching equipment includes two hydraulic flumes, 12- and 24-inches wide, which are equipped with pumps and circulation systems to produce open channel flows on adjustable slopes to study back water profiles, hydraulic jumps, drops, check dams, weir flows and orifice flows. A pipe network panel allows students to conduct tests on pipe friction and minor losses. An air tunnel apparatus produces turbulent air flows through a steel pipe approximately 20 feet long. A groundwater module demonstrates confined and unconfined aquifers, surface water/groundwater interaction, and subsurface contaminant transport.


The Environmental and Hydrology Laboratory is well-equipped for conducting physical, chemical and microbial analytical work for environmental research.

The laboratory is also used to conduct bench-scale tests on storm water related studies, including infiltration tests, clogging measurement, calibration of street inlet capacity, etc.

Major equipment and instruments include gas chromatographs, high-performance liquid chromatographs, UV spectrophotometers, automatic data collection system and molecular microbiology instruments.
