Dr. Chris Rehmann is a civil engineer whose research in hydraulics and environmental fluid mechanics includes flooding, stormwater runoff, and groundwater. His projects include experiments and modeling of differential mixing of salinity and temperature, the interaction of turbulence and double diffusion, mixing near bubble plumes, and boundary mixing in lakes. He has also worked on river mixing by assessing acoustic measurements of velocity, turbulence, and discharge and used acoustic measurements to determine dispersion in streams. He has applied his knowledge of mixing and transport in interdisciplinary collaborations involving the fate and transport of zebra mussel larvae, pathogens, and antibiotic resistance genes in rivers. Recent work on contamination caused by flooding involves a strong focus on environmental justice.
