<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This layer was generated by combining the VIMS Shoreline Studies Erosion Rates from 1937-2009 (Hardaway, Jr. et al. 2020) with the NOAA Coastal Resilience water interface shoreline (\\ccrmspace\ccrm\NOAACoastalResilience\GIS\Data\Shorelines\water_interface_shl\allVA_waterinterface_line_noboundaries.shp). The shoreline layer was first dissolved into a single multipart shoreline, and then split into 10 m segments using the QGIS v3.24 "Split lines by maximum distance" tool. The erosion rate points were then joined to their nearest shoreline segment, with a maximum search distance of 500 m. Shoreline segments greater than 500 m from the nearest erosion rate point were manually assigned a rate of -0.03 m/yr based on work done by Cielomar Rodriguez for her dissertation at VIMS. The 3 cm/year loss will only be valid in small creeks, and should not be used for the Seaside Eastern Shore or any shoreline along larger bodies of water (e.g., the Pamunkey River). The field "EPR_Mtr" is the erosion rate in meters. Segments where fields "n" and "distance" == 0 are where the line segments were more than 500 m from the nearest EPR point, and were therefore assigned a value of -0.03 m/yr.</SPAN></P></DIV></DIV></DIV> |
