Abstracts
Dr. Anthony Vodacek: "Assimilating Optical and Thermal Remote Sensing Data with Plume models in Lake Ontario"
For about the last 10 years a variety of radiative transfer models and analysis techniques have been used at the Digital Imaging and Remote Sensing Laboratory at RIT to understand both optical and thermal remotely sensed signals from Lake Ontario. I will describe how these models and techniques have been exploited to assimilate remote sensing data from different sensors with the detailed hydrodynamic modeling of the Niagara and Genesee River plumes. This approach is adaptable to coupled physical-biogeochemical models to enable improved environmental/ecological forecasting.
Dr. Dmitry Beletsky: "Modeling Thermal Structure and Circulation in the Great Lakes"
This presentation aims to paint a broad picture of large-scale physical processes in the Great Lakes. It summarizes results of hydrodynamic modeling conducted by the author in the last decade in the course of several major multidisciplinary projects (EEGLE, ECOFORE, Multi-Stress) on Lakes Michigan, Huron, and Erie. We start with a description of daily variations of temperature and currents during episodic events in winter and summer, subsequently discuss their seasonal cycle, and conclude with long-term mean characteristics. Ecological illustrations include the impact of currents on transport of sediments and biogeochemically important materials, larval fish advection and growth, and effects of wind on summer thermocline and hypoxia.
Dr. Venkatesh Merwade: "Hydrologic and Hydro-Climatic Modeling of Great Lakes Watersheds"
This presentation will highlight some of the modeling activities at watershed and regional scales in the Great Lakes region. In the first half of the presentation, development of a hydrologic model using the Soil Water Assessment Tool for the St. Joseph Watershed in the Maumee River Basin will be discussed. Specifically, the role of watershed sub-division, data resolution and parameters on model uncertainty will be presented. The second half of the presentation will focus on the effect of historical landuse change on the hydro-climatology of the Midwest region using Community Climate Modeling System. Comparison of change in hydro-climatology due to landuse and climate change will be presented.
Dr. Joseph V. DePinto, Todd Redder, Ed Verhamme: "Use of Spatial Data for Development and Application Of Great Lakes Ecological Models"
All environmental models require spatial data for input and calibration/confirmation. This presentation will briefly describe several ecological models that we have developed and applied in the Great Lakes and how spatial data have been employed in both the development and application of those models. Among the models that we have developed are:
- An ecological model (SAGMS) quantifying the effects of multiple stressors acting in concert on multiple ecosystem endpoints in Saginaw Bay, Lake Huron;
- A linked hydrodynamic-sediment transport-eutrophication model (LMR-MB) for analyzing the effects of human actions in the Maumee Watershed and hydrometeorological conditions on the sediment and algal dynamics in the lower Maumee River and western basin of Lake Erie;
- A physically-based, multi-media hydrophobic organic chemical model (GLMOD) of the entire Great Lakes basin that has been used to understand the air-land-water transport and fate organic chemicals of emerging concern; and
- An integrated ecological response model (IERM2) designed to inform decisions being made through the International Upper Great Lakes Study regarding the regulation of water levels and adaptation to potential climate change.
