Successes and Strategies for Numerical Models of the Chesapeake: Day 1


Session Date: June 1st 2016

Session Time: 1:00

Session Lead: Courtney Harris

Session Co-Lead(s): Raleigh Hood

Session Abstract:

Over the past decades, numerical models developed for the Chesapeake Bay and its airshed and watershed have become increasingly robust and useful for addressing both applied and fundamental questions.  Numerical models are used extensively for research and to guide management efforts in Chesapeake Bay and around the world. Many of these models are increasingly complex, however, and encompass several sub-models that each represents a complex system of equations that have been developed by experts in the relevant sub-field.  Though such large modeling frameworks may grow too complex for one person to fully comprehend, we rely on such systems to guide crucial management decisions that directly impact numerous stakeholder groups. Fitting with the theme of the meeting, various research communities have devised a range of strategies for ensuring that their methods and approaches achieve transparency for the end user.  Within this session we invite presentations of both well-established and newly developed community models for the Chesapeake Bay system.  The session will highlight recent advances in numerical modeling across the domains of the Chesapeake airshed, watershed and bay and the socioeconomic system, and also of the uses of those model results within a broad framework of understanding and managing the Chesapeake System.
