Abstract:
These data are polygons approximating the tidal water surface for a 50% annual chance coastal flood event in 2050 given a 19 inch sea level rise projection for 21 estuaries in Oregon. The water surface models are based on the combined flood height and sea level rise estimate. The flood event level was determined from water level exceedance analysis at NOAA tide gauges (the Crescent City, Charleston, South Beach, and Astoria tide stations). The sea level rise projections are from the National Research Council of the National Academies “Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future” (2012, pg 96). The water surface model was created using the National Oceanic and Atmospheric Administration (NOAA) VDatum tool. The land surface model is based on Lidar elevation measurements supplied by the Oregon Lidar Consortium (OLC) from 2008 and 2009. The polygon edges are the intersection of the modeled water surface and the Lidar Digital Elevation Model.
Purpose:
To visualize possible areas of flooding from a 50% annual chance coastal flood event in 2050. Part of a sea level rise exposure inventory of assets in Oregon's estuaries.

Data_Set_Credit:
Sea level rise projections came from the National Research Council (2012). Digital Elevation model based on 2008 lidar from Oregon Lidar Consortium. Water exceedance values are from NOAA CO-OPS. Randy Dana (DLCD/OCMP) processed the data to create the modeled flooding area. Work was funded through the NOAA Coastal Management Fellowship program.
