Climate change in the Chesapeake Bay will affect the effort to reach the TMDL, and maintain needed nutrient and sediment reductions. In an effort to determine how baseline nutrient and sediment loads will likely change in response to climate, and the best management practices (BMPs) being used to reduce them will function, a modified systematic review process was undertaken. Using this process we reviewed research literature and studies related to two primary questions: 1. How do climate change and variability affect nutrient/sediment cycling in the watershed?; and 2. How do climate change and variability affect BMP performance?


We want to thank and acknowledge the incredibly helpful and constructive comments from Julie Reichert-Nguyen, our steering committee (Raymond Najjar, Julie Shortridge, Kurt Stephenson, Lisa Wainger) and other reviewers including Lew Linker, David Wood, Alex Gunnerson, and Ken Staver. We are also grateful to Gary Shenk and Denice Wardrop for their valuable input. We also wish to thank members of the various Chesapeake Bay Program Goal Implementation Teams and workgroups that listened, and provided valuable input in response, to the numerous presentations dating back to 2020, particularly the Water Quality Goal Implementation Team, Climate Resiliency Workgroup, Modeling Workgroup, and Urban Stormwater Workgroup.
