The Hydrology, Water Resources, and Environmental Fluid Mechanics group maintains the Environmental Flows and Transport Processes Laboratory. This laboratory contains state-of-the-art facilities and instrumentation for investigating environmental fluid mechanics, transport processes in porous media, and reactive transport phenomena. Facilities include two recirculating turbulent water flumes, soil-moisture and soil property characterization systems, flow cells for fractured rock and porous media experiments, and an analog glacier flume. Instrumentation includes a laser-Doppler anemometer, an acoustic-Doppler anemometer, three lasers, laser-induced fluorescence equipment, in-situ tracer sensors, and high-resolution digital image acquisition systems. High-performance computing facilities are available for modeling environmental flow and transport processes and hydrologic systems.
