Simulations and Analysis of Physical, Chemical, and Biological Processes Affecting Water Quality in Freshwater
These researchers have developed deterministic, unsteady, year-round lake and stream water quality/ecosystem simulation models and are expanding, validating, and applying them. These models simulate a multitude of physical, chemical, and biological processes and give, for example, 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, and effects of hydro-thermal processes in watersheds at various stages of urban development on coldwater (trout) streams. MSI resources are used directly in the simulation of lake hydrodynamics and lake and stream water quality or for data analysis, and protection of coldwater fish habitat in Minnesota lakes from global warming.
