Simulating Flows and Loadings from the Watershed: Challenges and Solutions with Multiple Models at Multiple Scales


Session Date: June 2nd 2016

Session Time: 1:00

Session Lead: Bill Ball

Session Co-Lead(s): Gary Shenk, Zachary Easton, and Ciaran Harman

Session Abstract:

Watershed models have been used to inform decision-making by the Chesapeake Bay Program (CBP) partnership since the early 1980s.  The current development version of the CBPs Watershed model is constructed to incorporate knowledge from other modeling efforts.  Many questions exist as to how future changes in the CB system or its boundary conditions (e.g. climate, land cover, land use and management, changing conditions in lakes, reservoirs, and rivers) might affect changes in the timing, amounts, and spatial distributions of both water and pollutant loads.  Answering such questions will require the application of new modeling tools developed for application at a wide variety of spatial and temporal scales and tuned to new kinds of calibration data that allow the models to capture basic mechanisms related to those aspects of the system that are most fundamentally critical to its performance in processing water, nutrients, sediments, and other types of pollutants.  This symposium session invites scientific talks about new models andor new approaches to model application and use (particularly calibration and verification) that will address any one or more of the above defined issues.  Presentations that address issues of model and data accessibility, interoperability and transparency will be especially encouraged.
