The main outcome of the meeting were the following short, intermediate and long-term goals:

Short term

  • Recognize the Chesapeake FRG to be the academic research arm of the Chesapeake Community Modeling Program.
  • Populate the Chesapeake FRG pages with existing open-source Chesapeake Bay region models.
  • List publications which have used these models.
  • Post links to freely available model forcing data, such as bathymetry, wind, runoff, etc.
  • Pursue avenues for group proposals including funding for full-time of nearly full-time Chesapeake FRG oriented personnel, such as a dedicated post-doc.
  • Give priority to Chesapeake FRG related projects which focus on models with management implications, such as land use, water quality, ecosystem function, storm surge, etc.

Intermediate term

  • Implement a version of ROMs for the Chesapeake Bay at CSDMS in IRF format. Promising candidates include CHIMP and/or ChesROMS.
  • Implement the EPA/NOAA Chesapeake Bay models at CSDMS in IRF format.
  • Post key common forcing data sets at CSDMS.

Long term

  • Implement additional distinct, swappable land use models, hydrodynamic models, water quality models, ecosystem models, etc., in IRF format at CSDMS.
  • Utilize CSDMS to make side-by-side comparisons of model performance and differences in output by systematically swapping model components.
  • Utilize CSDMS to perform ensemble modeling (i.e., using multiple distinct models) of future Chesapeake environmental conditions under various management scenarios

April 2009 Meeting

The CCMP FRG had its first meeting on April 3rd at the Chesapeake Bay Program Office in Annapolis. The meeting was held to:

  1. get everyone up to speed on CCMP, CSDMS and model integration pathway that CSDMS is employing (modified CCA for the Architecture and framework, BABEL as the language independent compiler, modified OpenMI for interface standards etc etc),
  2. get everyone up to speed on appropriate Chesapeake modeling tools in use by the CCMP community,
  3. get everyone up to speed on the valuable field data that CCMP offers for code testing,
  4. develop some simple, doable short term, intermediate term and longer term goals for the group, and
  5. assign some tasks to the members

Presentations from the meeting can be found at: Chesapeake FRG meeting 2009#Circulars_and_Program.

The following target goals were formulated by attendees. Each one identified his areas of interest and responsibilities. Here is what we have:


  • CCA application in the Bay area. Do a simple application. Couple some models.
  • we need new people, students and technical staff - teaching and training - getting more funding
  • ChesROMS has some add-ons - work with ROMS and bring it in as a component
  • Consider getting new hires to work with Bay projects at CSDMS and to work with the CCA and CSDMS standards here


  • Data-model integration - how do they talk? - what are the tools? - synchronizing data and models
  • HIS people are working on observational models to go to different sources of data and pull it in in a standard format - WaterML
  • Visualization tools -
  • PIHM - sediment model - 3D equations - solute transport - all this will go to the CSDMS site - already on SourceForge - working on NetCDF - non-structured grid
  • Get a person who can spend time at the Boulder shop - write a proposal for an NSF fellowship - get money to fund this person at CRC
  • Short statement for this hire


  • Find funding for dedicated person
  • Joint CSDMS/CCMP person - industrial consortium - find corporate moneys - work with Kevin


  • Using ROMS for sediment transport - version of ROMS that is usable - a module in CSDMS
  • Connect ROMS with other models - get a generic ROMS with clearly identified connections to use in various applications
  • 1-D applications GOTM - open source, in Germany - can become a module - Tom Hsu
  • Data assimilation


  • Urban watersheds - assimilating data from dense networks - using different existing models
  • CUASHI HIS interaction
  • Coupling urban growth and hydrologic models - how to integrate Urban modules


  • Matlab to Python
  • Sediment transport models


  • Sediment transport models and mechanisms
  • Computational tools for people who don’t have much skills - small simple codes in Visual Basic -
  • Interoperability
  • 1D routing model Corps HEC RAS - get it into open source
  • Using high resolution topography - GIS
  • Portal to CSDMS has to be more enticing - needs coordinating documents - needs other formats


  • Model applications
  • Putting fully functional models on the web site - posting applications together with data - SIMS database
  • Model wrappers
  • Use BOINC - set up a distributed computational project


  • Applied models driven by users. Participatory modeling.
  • Models for decision support
  • Liking between models and frameworks of various complexity and scale
  • Integrated modeling
  • Help to write a proposal to hire a CSDMS/CCMP liaison programmer
