Research Description

Evan Variano is a professor in the Department of Civil and Environmental Engineering. His research is focused on experimental techniques, and the use of these to illuminate the dynamics of transport and mixing in natural water bodies. Sediment transport can be measured with digital video obtained via fiberoptic transmission. Transport of biologically relevant gasses CO2 and O2 can be measured with fluorescent dyes that signal the presence of such gasses in their dissolved (aqueous) phase.  Motion of particles suspended in turbulent flow can be measured by fabricating special optically-transparent particles.  Each of these techniques, and others, are applied in the laboratory and, whenever possible, in the field. Laboratory devices are designed to provide models of phenomena that occur in field settings.  Theoretical expertise focuses on turbulence and how it influences the transport of material near interfaces.
