Research: Restoration and Ecologically Designed Riverine Systems
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. FORT scientists have been designing and testing river restoration and engineering actions to achieve desired species or ecosystem services (e.g., wetland creation for wastewater treatment, saltcedar removal and subsequent revegetation, riparian plantings, flow prescriptions, and hydraulic design of channel habitat features), as these products demonstrate:
