Expertise in large river research provides science information to inform decisions on river management and restoration in the Midwest Region. Connectivity is a fundamental concept in river ecology and refers to opportunities for water to flow along and through riverine ecosystems. It is considered one of the primary drivers of river productivity, biological diversity and ecosystem health.
