BROWN BAG SEMINAR: Developing Tiered Environmental Flow Criteria Using a Functional Flows Approach for California Streams

Establishing environmental flow targets to protect aquatic communities is a priority for numerous programs in California including in the Delta. In this first of three brown bag seminars focusing on flow targets and ecology, Dr. Yarnell discusses her recent work using a functional-flows approach to develop statewide environmental flow recommendations. The approach allows for the rapid development of flow regimes […]

Integrated ecosystem modeling for adaptive management: Lessons from 40 years of decision support in the Great Lakes

Limnotech’s Dr. John Wolfe presents two case studies from the Great Lakes which utilized integrated modeling and adaptive management to solve ecosystem issues The Sacramento-San Joaquin Delta is no doubt a complex ecosystem, but it certainly is not the only one; the complexity and uncertainties facing the Bay-Delta system present challenges similar to those in the Great Lakes system.  In […]

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 […]
