DiLorenzo, J.L., Ram, R.V., Huang, P-S, and Najarian, T.O July 1994 - Pollution Susceptibility of Well‑Mixed Tidal Basins Journal of Waterway, Port, Coastal and Ocean Engineering, American Society of Civil EngineersAbstract:
This paper describes the development and application of a methodology for screening nonpoint-source-pollutant impacts on small (i.e., well-mixed) tidal basins. This methodology is based upon a simplified, filtering-response model for inlet/basin systems. This model relates the pollution susceptibility of well-mixed tidal basins to the forcing effects of tides, freshwater inflows, and basic system parameters. When coupled with an analogous nonpoint pollutant-loading model, the simplified receiving-water model provides first-order estimates of the embayment water-quality response to such loadings. This approach is applied to several small tidal embayments bordering the Hudson River Estuary. The model provides a ranking of the pollution susceptibility of these embayments, and a comparative assessment of their response to long-term nonpoint pollutant inputs. Thus, those embayments most influenced by nonpoint-source loadings can be identified by an assessment of basic embayment and watershed parameters.
