Lateral Marsh Edge Erosion as a Source of Sediments for Vertical Marsh Accretion

Charles S. Hopkinson, James T. Morris, Sergio Fagherazzi, Wilfred M. Wollheim, Peter A. Raymond
2018 Journal of Geophysical Research - Biogeosciences  
Marsh edge erosion, based on a comparison of 2005 and 2011 LiDAR data, provides 10,032 MT yr À1 . This level of erosion is met by <0.1% of total marsh area eroded annually.  ...  We quantified input of sediment from rivers and erosion of marsh edges. Maintaining elevation relative to the recent sea level rise rate of 2.8 mm yr À1 requires input of 32,299 MT yr À1 of sediment.  ...  The low relief of the Parker and Ipswich River watershed, however, will likely not translate into landslides as observed in more mountainous regions of New England.  ...
