Water Quality Screening Model Framework for Estuaries: Preliminary Application to Long Island Sound.

摘要

The screening model framework has been developed as part of NOAA's evolving National Estuaries Program (NEP) to provide 'first cut' order of magnitude assessments of resource-use problems and issues affecting marine resource development and conservation throughout the entire Nation. It uses readily available information and is generally designed for easy application to any system. The model is diagnostic in nature and does not replace the need for more sophisticated predictive modeling. It serves as a yardstick against which to assess relatively quickly and inexpensively alternative estuarine management strategies on a basinwide basis, and provides guidance in the development of more advanced modeling approaches that may be needed. The report describes briefly the Phase I application of NOAA's Water Quality Model Framework to Long Island Sound in support of EPA's Region 1 Bays Program. It addresses the pollutant transport behavior of the system as it is reflected in the distribution of salinity within the sound under varying hydrodynamic assumptions.
