Abstract Sediment introduction is a corollary of river- associated freshwater inflow in many estuaries. These sediments represent an asset relative to delta building and associated estuarine wetlands, a liability in maintaining navigation access. A multipurpose approach to resolving this conflict is the separation of navigation from sediment-laden freshwater inflow. Such a separation, as authorized for the Colorado River, provides dual benefits: reduced maintenance dredging and increased fish and wildlife resources. In contrast, failure to do so at the Lower Atchafalaya River, Louisiana, increasingly results in dual cost. Comparison of the two projects raises serious questions about the consistency of project evaluation and cost/benefit analysis.
