Effective river management depends on understanding the relations between variables—both the expected responses to alternative management actions and the management actions required to produce a desired objective. Describing and quantifying these relations improve the foundation on which river management decisions are made.
An important long-term focus of riverine science at FORT is on connections between physical and biological factors, processes, and effects. In recent work, FORT scientists have addressed more biotic interactions and reciprocal influences of biota on the physical environment (e.g., competition, riparian herbivory, hydraulic effects of riparian vegetation, invasive species). The following publications are examples of this work:
