It computes the mean shoreline displacement for the identified coastal segment by dividing the cliff (or beach) area variation, i.e., the area between the two coastlines, by the segment length, i.e., the average length of the two used shorelines [93], providing the mean displacement for the considered study sector [94] ...

End Point Rate (EPR): The End Point Rate is simply the Net Shoreline Movement divided by the time interval. Linear Regression Rate (LPR): uses shoreline locations to “fit” a line that approximates the trend of the data. The trend line is computed so that the offset between the line and the data points is minimized.

Shoreline change refers to the loss or gain of land area, or change to the landscape on the marine edge. It is an important indicator of environmental threats at coastal park beach areas.

The EPR is calculated simply by dividing the distance between 2 shorelines by the time (number of years) between those 2 shorelines.

In the present study, we generated shoreline change rates for the marshline shoreline proxy using the end point rate (EPR) method. The EPR is calculated simply by dividing the distance between 2 shorelines by the time (number of years) between those 2 shorelines.

The changes are caused by changes in the forces that move the sand, namely wind, waves, and currents, and by the supply of sand. Short- and long-term relative sea-level changes also control shoreline movement.

OverviewThe Digital Shoreline Analysis System (DSAS) is a freely available software application that works within the Esri Geographic Information System (ArcGIS) software. DSAS computes rate-of-change statistics for a time series of shoreline vector data.
