ECOL’s research involves water movement and water quality in natural and built environments, from porous media to lake hydrodynamics to coastal processes. Research activities involving combinations of laboratory, field and theoretical work, to investigate questions in different environmental compartments. The group completed numerous projects on soil and aquifer remediation, vadose zone flow, and hyporheic exchange, often based on coupled models of porous media flow and biogeochemical reactions. Recent projects have mainly focused on understanding physical phenomena in large water bodies such as lakes, using Lake Geneva as a large, outdoor laboratory.
