Abstract:

A three-dimensional numerical hydrodynamic model of Delaware Bay is being developed to assess the impact of deepening the navigation channel from near the mouth of Delaware Bay to the Philadelphia, Pennsylvania, and Camden, New Jersey harbors (Figure 1). Since previous studies have shown that a substantial fraction of the subtidal volume exchange in the Delaware estuary is associated with the exchange through the Chesapeake and Delaware Canal (C&D Canal), the numerical model includes not only Delaware Bay but also the C&D Canal and upper Chesapeake Bay from Annapolis, Maryland northward. A field data collection program is providing the necessary data for model verification. These data include water-surface elevation, velocity, salinity, and temperature at three depths at several long-term stations. In addition, two different two-week surveys are providing similar data at multiple locations across several ranges. Preliminary results from application of the 3D model using October 1992 data are presented. Detailed verification results will be presented at the conference.
