We have reorganized our Research Programs. Most of the research projects from this program are now organized under the Physical Environment Prediction Research Program.
GLERL HYDRODYNAMICS AND PHYSICAL PROCESSES RESEARCH PROGRAM
There are two primary components within this research
program:
Hydrodynamic Modeling, and Nearshore and Open-Lake Hydrodynamics.
This program supports research on physical processes in large lakes and the coastal ocean and their relationship to the biology, chemistry, and geochemistry of the ecosystem. This research is used to develop models to identify, forecast, and assist in managing and/or mitigating water quality and natural resource problems. Wind, waves, and thermal structure are primary determinants of water movements, mixing, and circulation in large lakes and (along with tides) in coastal ocean areas. The movement and mixing of water in natural systems affects water quality, biological community structure and productivity, and both sediment and contaminant transport, especially in nearshore areas. This research program also provides tools for more effective management of water resources: new or improved circulation and wind models and other products that assist in marine hazard prediction, emergency response, or damage prevention and reduction.
Hydrodynamic Modeling Program
(Task Leader: David Schwab) Develop and implement a system of computer-based models that can simulate and predict the 3-D structure of currents, temperature, water levels, wind-waves, and sediment transport in the Great Lakes; and integrate these models with real-time observations, to produce timely forecast products; apply these models to practical problems of coastal environmental management and planning.
Current Projects
- Lake Circulation Studies and the Great Lakes Coastal Forecasting System (GLCFS)
- Lake Erie Integrated Program
- New Bathymetry of the Great Lakes
- Real-time Meteorological Observation Network
- Modeling the Influence of Lake Circulation Patterns, Upwelling Events, and Turbulence on Fish Recruitment Variability in Lake Michigan
