Models & Data

Welcome to the CCMP Models page, your gateway to open-source models, data sources, and links to various modeling activities and resources. CCMP's collection of modeling and data resources is always growing, so be sure to check back frequently. If you feel you have anything at all to add to this page, please contact CCMP, as we would love to hear from you.

Watershed

Chesapeake Bay Program's Watershed Model

The Chesapeake Bay Community Watershed Model is an implementation of the HSPF model for the full Chesapeake watershed. Using this model, a group can determine the nutrient and sediment loads delivered to the Bay under various management strategies. By installing this model, supplying data on management practices, land use, and/or other relevant factors, and following the steps to run the model, users can determine the loads that result.

Phase 5

PIHM (Penn State Integrated Hydrologic Model)

The Penn State Integrated Hydrologic Model (PIHM) is a multiprocess, multi-scale hydrologic model where the major hydrological processes are fully coupled using the semi-discrete finite volume method. The model itself is "tightly-coupled" with PIHMgis, an open-source Geographical Information System designed for PIHM. The PIHMgis provides the interface to PIHM, access to the digital data sets (terrain, forcing and parameters) and tools necessary to drive the model, as well as a collection of GIS-based pre- and post-processing tools. Collectively the system is referred to as the Penn State Integrated Hydrologic Modeling System. The modeling system has been written in C/C++, while the GIS interface is supported by Qt. The Penn State Hydrologic Modeling System is open source software, freely available for download at this site along with installation and user guides.

SPARROW (Spatially Referenced Regressions On Watershed Attributes)

SPARROW relates in-stream water-quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and factors influencing terrestrial and stream transport.

Hydrodynamic Circulation

ChesROMS (Chesapeake Bay ROMS Community Model)

The MerhabChes program is developing a ROMS model of the Bay to be run in operational mode (ie, once a day). It will be used by the MerhabChes program to help in the prediction of Harmful Algal Blooms. The full implementation will be developed here, and all intermediate modeling results and methods will be available for public use and scrutiny. We hope to catalyze a new method of community modeling with involvement beyond the core researchers of the MerhabChes project.

C3PO

This is an implementation of the finite element model Quoddy. It was developed at the NOAA/CSDL as an aid to navigation. Daily runs of this model are posted to the NOAA Chesapeake Bay Office's web site: Daily Graphics and as the NetCDF files at DODS Server.

POM

This is a contribution from Xinyu Guo, ODU/CCPO. This implementation of POM has been calibrated for the Chesapeake Bay and uses the same NetCDF ouput file format as the above Quoddy implementation.

Chesapeake Interactive Modeling Project (CHIMP)

CHIMP ScreenshotCCMP member researchers have put together a very exciting interactive teaching tool. Jay Austin, Large Lakes Observatory, U. Minnesota, and his former Old Dominion colleagues, Jessica Crouch, Mike Dinniman, Yuzhong Shen, John Klinck, Elizabeth Smith, and Lee Belfore, have put together a slimmed down ROMS simulation of the Chesapeake Bay with an easy to use GUI. The tool allows students (myself included) to manipulate the physical forcing of the bay and quickly see results. The ability of this tool to develop intuition about the Bay is remarkable. Check it out here.

CE-QUAL-ICM 3-D Eutrophication Model

CE-QUAL-ICM Version 1.0 is a three-dimensional eutrophication model for the Chesapeake Bay and major tributaries developed by researchers at the U.S. Army Corps of Engineers Engineering Research and Development Center in Vicksburg, MS. This model study was sponsored by the Chesapeake Bay Program Office (CBPO), U.S. Environmental Protection Agency, and the U.S. Army Engineer District, Baltimore (CENAB).

BioGeoChemical Processes

Jiangtao Xu and Raleigh Hood's model of the biogeochemical processes in the Chesapeake Bay is presented with input files to run full year simulations for 1995 and 1996. The model was developed for Jiangtao Xu's dissertation.

Oyster larvae development simulation

An oyster larvae development model for the C. virginica larvae as a function of temperature, salinity, food concentration and turbidity concentration.

Chespeake Bay Oyster Larvae Tracking Tool and IBM Particle Tracker

The CBOLT tool allows a particle tracking ability to be accessed easily from a web page. The underlying models access the results of theC3PO model or the POM model to provide velocity fields. Particle tracking code was written in C++ to allow expansion to object oriented programming of IBM models. The “Oyster larvae development simulation” model may be embedded into the particle tracker to trace life histories of oyster larvae while they move about the bay.

The Oyster tracking tool, (oceanmodelfiles on SourceForge), is nearing completion and can be used with C3PO or the POM model output files. Future enhancements will be to connect the above oyster larvae development model within the particle motion of the program. The result will be an Individual Based Modeling system which will follow the life history of oyster larvae through both time and space.

Ecosystem-Based Management Tools Website

The EBM Tools Network has released a website with a database of ecosystem-based modeling tools. This site is brought to you by the EBM Tools Network, an alliance of EBM tool developers, practitioners, and training providers to develop EBM tools and support their use in EBM implementation in coastal and marine environments. Network members include Duke University, Ecotrust, The Nature Conservancy, NatureServe, NCEAS, NOAA, the Orton Family Foundation, the David and Lucile Packard Foundation, Princeton University, and the Sea Around Us Project.

Spatial Modeling Environment

The Spatial Modeling Environment is a software system which connects watershed modeling components to build comprehensive environmental modeling systems. Alexy Voinov, now at Univ. Vermont, worked with the SME and applications to the Patuxent Watershed.

Common Data Output Methods

This is another SourceForge project which is building standardized output file formats for use by the hydrodynamic models. Both the POM and C3PO models above use these tools. The Particle tracker and several OpenDAP web servers take advantage of the portibility of this standard.
