Chesapeake Bay Program Office is offering a grant for Multiple Tributary Models to Assess 2035 Climate Change Risk and Water Quality Challenges

This RFA is seeking insightful, expert, and cost-effective applications from eligible applicants to apply a state-of-the-science unstructured grid model to the tidal waters of the Chesapeake’s tributaries and embayments (hereafter called the Multiple Tributary Model or MTM). The management purpose of the MBM is to assess the Chesapeake tidal water quality standards including dissolved oxygen, chlorophyll a, suspended solids, water clarity, and SAV under current and future conditions of climate change to 2035 and beyond. The MTM scenarios, as directed by Chesapeake Bay decision-makers, will provide support for management strategies to achieve water quality standards in TMDLs and assessments in the tidal Bay (other than the 2010 Chesapeake TMDL). The 2010 Chesapeake TMDL will be assessed by the Phase 7 Main Bay Model (MBM) now under development. The MTMs and the MBM will be completed and fully operational by December 2025.
