Core Ecosystem Engineering Techniques for Coastal Wetlands

Hydrological Restoration

Altered water flow is perhaps the single most damaging impact on coasult wetlands. Dikes, levees, culverts, and drainage diches can disconnect thee wetland from tidal flushing, causing impoundment, hypersalinity, or refreswater stagnation. Hydrological reconvestionion rne re-estates natural water exchange: removing congreers, reveining undersized culverts, or constructing tidal gates that allow controlled doading.
