Simulations of Water Quality and Quantity in the Environment
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. Work is also ongoing on man-made water conveyance systems, including stormwater and wastewater transport and treatment. MSI resources are used directly in the simulation of lake hydrodynamics, lake and stream water quality, and hydraulics in natural and man-made open channel drainage systems.
