Midpoint Assessment

New web page summarizes the priorities and identifies lead researchers for each effort. The descriptions are brief with links to more detailed workplans.

Phase 7 Model Development

Evolving plans and related documents can be found on the Chesapeake Bay Program's Phase 7 Model Development webpage.

Tributary Summaries

The Chesapeake Bay Program and its partners produce tributary basin summary reports for the Bay’s 12 major tributaries using tidal monitoring data from more than 130 monitoring stations throughout the mainstem and tidal portions of the Bay. These reports use water quality sample data to summarize 1) How tidal water quality (TN, TP, DO, Chlorophyll a, Secchi Depth) has changed over time, 2) How and which factors may influence water quality change over time, and 3) Recent research connecting observed changes in aquatic conditions to its drivers.

These documents can be found on the CAST webpage here.

Phase 6 WQSTM Peer Review

This project page is the repository for documents and files related to the peer review of the Phase 6 Water Quality and Sediment Transport Model (WQSTM). Please email Kyle Hinson (khinson@chesapeakebay.net) with any questions you may have.

Documentation

All documentation for the Phase 6 WQSTM can be found in the Draft 2017 documentation and its appendices. Information on key scenarios can also be found in the Phase 6 Key Scenarios pdf file.

Additional Materials

Further attachments contain all the presentations that were presented for the STAC peer review.

CMAQ Peer Reviews

CMAQ Review Process: During the past three years, CMAS, in collaboration with EPA scientists, has organized two CMAQ review panel meetings etc. The first CMAQ review meeting was held during December 2003. The second meeting was held during May 2005. The review process usually starts by inviting a number of key scientists to participate in the process. The scientists are selected based on their expertise in accordance with the focus of the review session. After reviewing numerous reports and articles and completing their meeting in Research Triangle Park, North Carolina, the review panel prepares a comprehensive report on their findings and recommendations. EPA then responds to the comments of the reviewers. Final review reports are posted below.
