Beck 2021 data release DOI:10.5066/P9EHOBKO Pacific Coastal and Marine Science Center, Santa Cruz, CA U.S. Geological Survey https://doi.org/10.5066/P9EHOBKO This part of the data release presents projected flooding extent polygon (flood masks) shapefiles based on wave-driven total water levels for Commonwealth of Puerto Rico. There are eight associated flood mask and flood depth shapefiles: one for each of four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years), the pre-storm scenario (base) and the post-storm scenarios. These data are intended for policy makers, resource managers, science researchers, students, and the general public. These data can be used with geographic information systems or other software to identify and assess possible areas of vulnerability to wave-driven flooding. These data are not intended to be used for navigation. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Flood extent polygons were built by creating a minimum-bounding polygon between flood points along adjacent shore normal profiles for 4 modeled storm return periods (10, 50, 100, or 500 years) in current conditions and in post-storm conditions. The resulting 16 polygons were clipped and/or extended to a simplified coastline based on the 0-m contour used in the elevation model and edited to remove spurious results. The edited polygons were merged into a single shapefile (flood mask) and are identified by a unique floodmask attribute in the following format: PuertoRico_rp[#]_[scenario], where [#] = wave energy return period (10, 50, 100, or 500 years), and [scenario] = current conditions (base) or post-storm conditions. See Storlazzi and others (2021) for a detailed description of model development and methodologies.
