Coastal Submergence and Marsh Fringe Erosion

摘要: Coastal wetlands may shrink, expand, or remain constant in area during coastal submergence, depending on sedimentation rates the wetland surface comparison with of submergence. Losses are primarily reflected shoreline recession due to erosion and drowning. In Delaware Bay sea level rise, subsidence, dissection combining produce rapid a net loss wetIands as coast is submerged. Pamlico Sound, less severe, but still sufficient cause Along Atlantic Gulf plain, marsh more than about 0.3 m/yr (and perhaps much less) will result at greater rate new marshes can be created.
