Summary

The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. The shoreline position and change rate are used to inform management decisions regarding the erosion of coastal resources. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast. In 2013 two oceanfront shorelines for Massachusetts were added using 2008-2009 color aerial orthoimagery and 2007 topographic lidar datasets obtained from NOAA's Ocean Service, Coastal Services Center. This 2018 update includes two new mean high water (MHW) shorelines for the Massachusetts coast extracted [...]

Purpose

This mean high water (MHW) datum-based shoreline dataset was extracted using a profile method. The profile method for extracting shorelines was initially developed for open-ocean coasts. This shoreline does not have buoy data from which to gather wave data, so the run-up equations the profile method implements to estimate a proxy-datum bias value cannot be used. The region of the coast tends to have lower wave energy, which would result in less run-up and yield a smaller offset between a proxy shoreline and a datum shoreline than would occur along open-ocean coasts. When this datum-based MHW shoreline is compared to historic proxy-based high water line shorelines there may be some artificial seaward offset of the historic data that has not been quantified and could potentially influence the rates.
