Hydrodynamic and Water Quality Model Study of San Juan Bay Estuary

摘要

This report describes a three-dimensional hydrodynamic and water quality model study of the San Juan Bay and Estuaries system conducted to evaluate the effectiveness of various management alternatives for improving water quality. Alternatives included methods to increase flushing, reduce pollutant loadings, and combinations of the two. The CH3D-WES hydrodynamic model and the CE-QUAL-ICM water quality model were employed in the study. The models were indirectly coupled and were adjusted and calibrated against data collected during the summer of 1995. Analysis of various management scenarios revealed that a combination of widening and deepening of Cano Martin Pen a, filling of dredged submerged borrow pits, and removal of un-sewered loads in Cano Martin Pena provided the greatest water quality benefits.
