Book Description
This report describes the plans and specifications for a Florida Bay water quality model and provides tasks and schedules for its development and application. The model is required to address issues pertaining to nutrient inputs and associated impacts on water quality and sea grass, particularly as related to changes in freshwater inflows from south Florida through the Everglades and the Central and South Florida Flood Control Project. Modeling components discussed in the report include the hydrodynamic model; the water quality model, including submodels for the water column, benthic sediments, and sea grass; and the sediment transport model, which will also reside within the water quality model. Strategies for model calibration, confirmation, sensitivity analyses, and scenario testing are discussed. Data requirements and gaps are presented. Plans for technology transfer and partnering/collaboration are also discussed.

Book Description
This report is a product of the Committee on Restoration of the Greater Everglades Ecosystem (CROGEE), which provides consensus advice to the South Florida Ecosystem Restoration Task Force. The Task Force was established in 1993 and was codified in the 1996 Water Resources Development Act (WRDA); its responsibilities include the development of a comprehensive plan for restoring, preserving and protecting the South Florida ecosystem, and the coordination of related research. The CROGEE works under the auspices of the Water Science and Technology Board and the Board on Environmental Studies and Toxicology of the National Research Council. The CROGEE's mandate includes providing the Task Force not only with scientific overview and technical assessment of the restoration activities and plans, but also providing focused advice on technical topics of importance to the restoration efforts. One such topic was to examine "the linkage between the upstream components of the greater Everglades and adjacent coastal ecosystems." This report addresses this issue by breaking it down into three major questions: What is the present state of knowledge of Florida Bay ("the Bay") on scientific issues that relate to the success of the overall CERP? What are the potential long-term effects of Everglades restoration as currently designed on the nature and condition of the Bay? What are the critical science questions that should be answered early in the restoration process to design a system that benefits not only the terrestrial and freshwater aquatic Everglades but the Bay as well? This study was inspired in part by the 2001 Florida Bay and Adjacent Marine Systems Science Conference held on April 23-26, 2001 in Key Largo, Florida. An overlapping meeting of the CROGEE was held at the same location on April 26-28, 2001. The conference was organized by the Program Management Committee (PMC) of the Florida Bay and Adjacent Marine Systems Science Program. The PMC organized the conference around five questions suggested by the Florida Bay Science Oversight Panel. These questions related to circulation, salinity patterns, and outflows of the Bay; nutrients and the nutrient budget; onset, persistence and fate of planktonic algal blooms; temporal and spatial changes in seagrasses and the hardbottom community; and recruitment, growth and survivorship of higher trophic level species. Some of these issues are discussed in the present report. However, as noted earlier, this report focuses on the subset of questions that relate to linkages between the Bay and the upstream portion of the Everglades system that arose at the 2001 Florida Bay Conference.

Book Description
Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Book Description
Therefore, the statistical distribution that describes chlorophyll a concentrations in Hillsborough Bay was identified and robust confidence intervals were developed to better understand the uncertainty associated with chlorophyll a measurements. Previous work linked chlorophyll a concentrations in Hillsborough Bay to explanatory variables based on monthly estimates. These relationships were used to develop water quality targets for the system. In this study, the previously developed relationship was revisited, resulting in an improved statistical model that is more robust. This improved model can also be used to evaluate the previously proposed targets and to better predict future changes due to climate change, sea level rise, and management actions. Lastly, a new method was developed to estimate atmospheric temperature in the contiguous United States.

Book Description
Hydrodynamics and Transport for Water Quality Modeling presents a complete overview of current methods used to describe or predict transport in aquatic systems, with special emphasis on water quality modeling. The book features detailed descriptions of each method, supported by sample applications and case studies drawn from the authors' years of experience in the field. Each chapter examines a variety of modeling approaches, from simple to complex. This unique text/reference offers a wealth of information previously unavailable from a single source. The book begins with an overview of basic principles, and an introduction to the measurement and analysis of flow. The following section focuses on rivers and streams, including model complexity and data requirements, methods for estimating mixing, hydrologic routing methods, and unsteady flow modeling. The third section considers lakes and reservoirs, and discusses stratification and temperature modeling, mixing methods, reservoir routing and water balances, and dynamic modeling using one-, two-, and three-dimensional models. The book concludes with a section on estuaries, containing topics such as origins and classification, tides, mixing methods, tidally averaged estuary models, and dynamic modeling. Over 250 figures support the text. This is a valuable guide for students and practicing modelers who do not have extensive backgrounds in fluid dynamics.
