ERDC TN-SWWRP-07-3, The Ecosystem Concept and Linking Models of Physical-Chemical Processes to Ecological Responses: Introduction and Annotated Bibliography

چکیده
PURPOSE: The U.S. Army Corps of Engineers (USACE) is striving to design, evaluate, and manage its large-scale engineering projects in a sustainable, environmental context that extends beyond traditional project boundaries. This approach, which frames a project as part of a larger, functioning ecosystem, was articulated in “The Environmental Operating Principles” by the Chief of Engineers (Flowers 2002) and has been adopted by the System-Wide Water Resources Program (SWWRP). The goal is to promote environmental sustainability and sound stewardship by adopting an ecosystem view.

PURPOSE: This technical note presents the results of incorporating a fish bioenergetics module into CE-QUAL-ICM, a spatially explicit eutrophication model. In addition to fish consumption of algae, zooplankton, and detritus, fish biomass accumulation and recycling to the water column are explicitly accounted for. Schools of fish are tracked individually, allowing for spatial resolution of their...
