Description:
Abstract:
This part of the data release presents projected flooding extent polygon (flood masks) and flooding depth points (flood points) shapefiles based on wave-driven total water levels for the Territory of Guam. There are 8 associated flood mask and flood depth shapefiles: one for each of four nearshore wave energy return periods (rp; 10-, 50-, 100-, and 500-years) and both with (wrf) and without (worf) the presence of coral reefs. Flooding depth point data are also presented as a comma-separated value (.csv) text file.
Purpose:
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.
Supplemental_Information:
Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. Although this Federal Geographic Data Committee-compliant metadata file is intended to document the data set in nonproprietary form, as well as in Esri format, this metadata file may include some Esri-specific terminology.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
No formal attribute accuracy tests were conducted. Attribute values are extents of modeled flood projections due to extreme wave and sea-level conditions and presence or absence of coral reefs and therefore cannot be validated against observations. Values are within a reasonable and expected range.
Logical_Consistency_Report:
No formal logical accuracy tests were conducted. Values are within reasonable and expected range.
Completeness_Report:
Dataset is considered complete for the information presented as described in the abstract. Users are advised to read the metadata record carefully for additional details.

Complete explanation of data and methodology used to create flooding model.
Process_Step:
Process_Description:
Flood water depths were extracted from a grid of modeled total water levels for 4 modeled storm return periods (10, 50, 100, or 500 years) with and without the influence of coral reefs. Points were extracted every 4 meters along shore normal profiles with a 100 m alongshore spacing and saved as an ESRI point shapefile in the following format: [Sublocation]_rp[#]_[REEFSTATUS]_floodpoints, where [Sublocation] = one of 22 sublocations within the 7 main geographic areas of the States of Hawaii and Florida, the Territories of Guam, American Samoa, Puerto Rico, and U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands, [#] = wave energy return period (10, 50, 100, or 500 years), and [REEFSTATUS] = with reef (wrf) or without reef (wofr). See Storlazzi and others (2019) for a detailed description of model development and methodologies.
Process_Date: 2018
Process_Step:
Process_Description:
Flood water depth shapefiles were merged to create a single shapefile for each of the 7 main geographic areas of the States of Hawaii and Florida, the Territories of Guam, American Samoa, Puerto Rico, and U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands. A Scenario attribute was added to identify the wave-energy return period and reef status combination used to derive the flood depth based on the original shapefile.
Process_Date: 2018
Process_Step:
Process_Description:
The merged flood water depth shapefiles were exported as a text file in a comma separated value (.csv) format.
Process_Date: 2018
Process_Step:
Process_Description:
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) with and without the influence of coral reefs. The resulting 8 polygons for each geographic sublocation area 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 MaskName attribute in the following format: [Sublocation]_rp[#]_[REEFSTATUS]_floodmask, where [Sublocation] = one of 22 sublocations within the 7 main geographic areas of the States of Hawaii and Florida, the Territories of Guam, American Samoa, Puerto Rico, and U.S. Virgin Islands, and the Commonwealth of the Northern Mariana Islands, [#] = wave energy return period (10, 50, 100, or 500 years), and [REEFSTATUS] = with reef (wrf) or without reef (wofr).
