Ecosystem Modeling to Support Adaptive Management – Lessons from 40 years of Decision Support for the Great Lakes


Managing large interconnected systems of water bodies presents complex challenges, and model simulations are an essential tool.  For many years, the Great Lakes community has used models to support management of their system.  The complexity of the Bay Delta system presents similar challenges. Adaptive management will be critical, given climate change and other uncertainties.  This presentation provides lessons learned from […]
