Evaluation of Multiple Shallow-water Systems Analysis

In Progress

An exploration of how shallow-water models can improve shallow-water simulations of dissolved oxygen, chlorophyll a, suspended solids and water clarity to better understand the impacts of alternative management strategies on water quality and living resources in the tidal Chesapeake Bay.

Description

The U.S. Environmental Protection Agency's Chesapeake Bay Program Office worked with principal investigators (PIs) to provide Chesapeake Bay Program partners with proposals for the application of shallow-water models to improve Chesapeake Bay shallow-water simulations of dissolved oxygen, chlorophyll a, suspended solids and water clarity in order to better understand the impacts of alternative management strategies on water quality and living resources in the tidal Chesapeake Bay. The RFPs cover the evaluation of the multiple, developed shallow-water models. Over the course of the two-year project, multiple modeling teams were funded to apply different shallow-water models using common forcing conditions over a three– to five–year-base-case run at specified shallow-water sites. The U.S. EPA also funded an independent model evaluation team that used state-of-the-art metrics to assess the relative skill of these shallow-water models based on available water quality and submerged aquatic vegetation (SAV) monitoring data. The independent model evaluation team also compared the results from a series of nutrient and sediment change scenarios and analyzed causes and impacts of differences among the shallow-water models.
