Hydrodynamic design in coastal wetland restoration
Coastal wetlands in California are critically positioned at the interface between increasingly developed watersheds and the coastal ocean. These wetlands provide habitat for fish and wildlife, provide nutrients to surrounding coastal waters, and create recreational opportunities (Mitsch and Gosselink 1986). This report describes a circulation and transport model that is designed for tidal wetland circulation and mixing studies. Given the importance of wetland restoration projects to offset the impact of coastal development, wetland circulation and mixing models are of great utility for evaluating the advantages and disadvantages of various wetland restoration alternatives relative to issues such as bathing water quality, eutrophication, and sedimentation. An application of the model to a restored wetland and guidelines for its use are presented.
