Future Technologies of Numerical Modeling of Chesapeake Bay
Session Date: May 28th 2010
Session Time: 12:33
Session Lead: Frank Aikman
Session Co-Lead(s): Richard Patchen, Lyon Lanerolle1, Raghu Murtugudde and Raleigh Hood
Session Abstract: Presently, there are many numerical modeling efforts underway in the Chesapeake Bay. These cover a multitude of numerical ocean models (e.g. ROMS, CH3D, etc.), physical and biogeochemical/ecological model applications and both research and operational modeling set-ups. There is also a large volume of observational measurements available for the Chesapeake Bay spanning many years which have yet to be fully utilized. This session aims to discuss some future numerical modeling techniques and technologies, in particular, (I) nesting, (ii) data assimilation, (iii) watershed modeling and their integration into the hydrodynamic modeling, (iv) wetting-drying, (v) inclusion of freshwater fluxes, (vi) sediment transport and exchanges, and (vii) new bulk flux formulations (e.g. a successor to the well known TOGA-COARE formulation, etc.) which have yet to be routinely used in the Chesapeake Bay numerical models in combination with the available observations. In addition to the above physical modeling enhancements, there also exist many corresponding ecological modeling and biochemical-physical coupling enhancements. There are three aims for this session: (a) to provide researchers and investigators an opportunity to present their efforts and findings on the above physical and ecological modeling and technology advances; (b) to initiate a dialogue regarding which of the above items are the most critical to the next generation of Chesapeake Bay numerical modeling setups and how best to go about incorporating them in the currently available models; and (c) develop plans for the best options for future projections of Chesapeake Bay circulation, ecosystem health, and interactions with land use changes and other human activities.

Post-Session Review: This session provided a forum and opportunity for investigators to present their efforts and findings associated with physical (hydrodynamic) and ecological (biochemical) modeling and technology advances. It did initiate a dialogue regarding what technologies are the most critical to the next generation of Chesapeake Bay numerical modeling setups but it fell short of developing plans for the best options for future projections of Chesapeake Bay circulation, ecosystem health, and interactions with land use changes and other human activities.
Talks in this session covered a number of modern numerical modeling techniques, technologies and applications in the Chesapeake Bay region. These included:
- model nesting techniques using ROMS for restoration activities at Poplar Island (Lanerolle)
- model simulation of ground water transport of nitrates in the Delmarva Peninsula (Sanford)
- data assimilation via a Local Ensemble Kalman Transform Filtering technique (Hoffman)
- development of a Mid-Atlantic/Ches & Del Bays (MACROMS) modeling system and coupling to a larval transport algorithm (Long)
- benthic exchange and mud representation in a 3-D hydrodynamic and sediment transport model in the York River (Harris)
- an update on FEMA coastal hazard analysis and creation of Digital Flood Insurance Rate Maps (DFIRMS) (Gangai)
