Comparing Models of Chesapeake Bay and its Watershed

Description

The Chesapeake Bay Program watershed and estuarine models have provided the foundation for research and management-oriented modeling activities in the Bay for more than a decade. However, in recent years several new models have been implemented that are based upon entirely different codes. These include hydrodynamic models (e.g., ROMS, Quoddy, ELCIRC), estuarine water quality models (e.g., based on Fennel et. al., 2006, and other NPZD-type formulations) and watershed models (e.g., GWLF, SWAT and PIHM). At present, there is not very much interaction among the groups that are developing these different models.

This workshop is intended to bring these various development groups together to promote collaboration and sharing of modeling-oriented resources. In addition, we will explore how these models differ in terms of their formulations, grid structures and implementations and we will discuss their relative strengths and weaknesses in the context of Chesapeake Bay. In this workshop we will also explore how we might go about making some quantitative model intercomparisons in the future.

Open Discussion

In an open discussion forum we will explore how different estuarine and watershed models differ in terms of their formulations, grid structures and implementations and we will discuss their relative strengths and weaknesses in the context of Chesapeake Bay. We will also discuss how to move forward with making quantitative model intercomparisons in the future.
