Description:

Abstract:

This data release provides flood depth GeoTIFFs based on sea-level rise for the coast of the most populated Mariana Islands of Guam and Saipan. Digital elevation models were used to extract sea-level rise flooded areas at 10-m2 resolution along the coastlines for +0.25 m, +0.50 m, +1.00 m, +1.50 m, +2.00 m, and +3.00 m sea-level rise scenarios.

Purpose:

These flood extent files were created to evaluate coastal flooding in the most populated Mariana Islands of Guam and Saipan due to climate change and sea-level rise. The data are intended to provide a spatially explicit, rigorous valuation of how, where, and when climate change and sea-level rise increase coastal storm-induced flooding to help identify areas where management and/or restoration could potentially help reduce the risk to, and increase the resiliency of, the coastal communities in populated Mariana Islands. The data can be used with geographic information systems (GIS) software for research purposes. The methods follow a sequence of steps derived from Storlazzi and others (2019, 2021) and Reguero and others (2021) that integrate physics-based oceanographic and coastal engineering modeling, along with ecologic and geospatial data and tools, to quantify the role of climate change and sea-level rise in increasing coastal flooding hazards.

Process_Step:

Process_Description:

Extract SLR flood scenarios (0.25, 0.5, 1.0, 1.5, 2.0 and 3.0 m) for the coast of Mariana Islands of Guam and Saipan from DEMs, by first extracting values from 0 to SLR elevations. Then these layers were changed to flood depths by subtracting extracted values layer from SLR height, creating flood depths GeoTIFFs. The corresponding SLR storm flood extents for 1-year storms were then used to clip the extents of the SLR only flood extents to ensure that any clipping of the original storm flood layers was honored in the SLR flood extents. These new clipped GeoTIFFs were then exported out as polygons. These new polygons were then visually inspected to remove any polygons that could not be the result of SLR flood inundation. Once this inspection was complete, these edited SLR flood extents were then used to clip the SLR flood depths GeoTIFFs for a final time. Final GeoTIFFs were separated by island and zipped (SLR_[island]_depths.zip) for file-size considerations.

Overview_Description:

Entity_and_Attribute_Overview:

GeoTIFFs contained in this part of the data release include projected flood extents in the following format SLR_[Island]_[sea-level rise scenario].tif, where [sea-level rise scenario] = one of the 6 sea-level rise scenarios modeled (025cm, 050cm, 100cm, 150cm, 200cm, 300cm). Files are grouped by island, containing all sea-level rise scenarios. For example, SLR_Guam_depths.zip contains all outputs for Guam within which SLRGuam_300.tif illustrates the flood depths for a sea-level rise of 300 cm (3 m).
