Hydraulic Geometry: A Geomorphic Design Tool for Tidal Marsh Channel Evolution in Wetland Restoration Projects

摘要: Empirical hydraulic geometry relationships for tidal marsh channels are a practical geomorphically based design tool that can assist in the planning of wetland restoration projects. This study provides predicting depth, width, and cross-sectional area mature as functions contributing or prism. The on data from San Francisco Bay coastal salt marshes ranging size 2 to 5,700 ha. These refine expand earlier relationships. Relationships be used predict direction rate evolution channel an immature perturbed system. Channel three youthful channels, ages 4 13 years, suggest converging their predicted equilibrium morphology. Two eroding response significant increases upstream They have enlarged first by deepening, one case after years beyond then widening through slumping banks. third channel, new forming depositional mudflat, is its morphology but will likely take several decades equilibrate.
