This paper describes a domain decomposition methodology used in the application of the three-dimensional environmental fluid dynamics code, EFDC, to model hydrodynamics and transport in the Chesapeake Bay estuarine system. The model application encompasses a hierarchy of spatial grid resolutions in the main stem of the Chesapeake Bay, the adjacent continental shelf and the major sub estuary tributaries. The rationale for this approach is to provide a coherent modeling framework for analyses and predictions ranging from small scale localized phenomena in the tributaries to large scale phenomena characterized by significant interactions between the shelf, the main stem of the bay and major tributaries.
