These researchers have developed deterministic, unsteady, year-round lake and stream hydrodynamic and water quality/ecosystem simulation models and are expanding, validating, and applying them. These models simulate a multitude of physical, chemical and biological processes and show, for example, waves and currents, water temperature, dissolved oxygen, primary productivity and fish habitat distributions in various classes of lakes, rivers, and streams, including both open-water conditions and the ice-cover period. Simulations can be made for continuous long-term periods (e.g. 30 years), or for periods of a few days on individual water bodies with high temporal resolution. Recent work has included simulations of wind-driven currents in the Great Lakes, the distribution of wind stress in the atmospheric boundary layer over a lake surface, solute transport across a sediment/water interface in streams and lakes, wave energy impacts on fish spawning habitat, and effects of hydro-thermal processes in watersheds at various stages of urban development on coldwater (trout) streams. Current work includes studies on open channel flow metering and solute transport through soil columns. MSI resources are used for numerical simulations of chloride transport through soils (using Comsol or custom code) and for running CFD simulations of critical flow venturi flumes for flow metering.
