The data sets provided here consist of 2D XBeach model files and sample input files used for Coastal Storm Modeling System (CoSMoS) simulations of flood and erosion hazards in Elim, Alaska. The models produce outputs for a suite of hazard products (see products in this release), such as flood depths, flood extents, and erosion and sedimentation. In this release, example forcing files for conditions with a 100-year return period coastal storm and a sea level rise of 0.5 m are provided, in addition to all ...

Erosion and sedimentation maps resulting from compound coastal hazards —specifically sea-level rise (SLR) and projected coastal storms-are provided for Elim, Alaska. These products are consistent with other data in this release (for example, flood extent and velocity hazards; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTIFFs) for 30 storm and SLR combinations (SLR scenarios 0, 0.5, 1.0, 1.5, 2.0, and 3.0 ...

Flood depths from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Elim, Alaska. These projections focus on areas landward of the present-day shoreline. The flood depth products are consistent with other data in this release (for example, flood extent and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTiffs) for 36 storm and SLR ...

Flood extents, as well as the upper and lower uncertainty bounds of flood extents, from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Elim, Alaska. These products are consistent with other data in this release (for example, flood depths and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as shapefiles for 36 storm and SLR combinations (SLR scenarios ...

Velocity hazards (maximum depth times velocity) from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Elim, Alaska. Velocity hazards are a measure of the velocity severity. Categories range from 0 (low hazard) to 4 (extreme hazard) following guidance from the Federal Emergency Management Agency (2020). These products are consistent with other data in this release (for example, flood extent and event-driven erosion; Erikson and others, 2025), ...

Water elevations from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Elim, Alaska. These products are consistent with other data in this release (for example, flood extent and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTIFFs) for 36 storm and SLR combinations (SLR scenarios 0, 0.5, 1.0, 1.5, 2.0, and 3.0 meters combined with 1 ...

Wave hazards (wave heights) from compound coastal hazards—specifically sea-level rise (SLR) and projected coastal storms—are provided for Elim, Alaska. These products are consistent with other data in this release (for example, flood extent and event-driven erosion; Erikson and others, 2025), supporting integrated coastal hazard assessments for Alaskan communities. The data are provided as gridded maps (GeoTIFFs) for 30 storm and SLR combinations (SLR scenarios 0, 0.5, 1.0, 1.5, 2.0, and 3.0 meters ...
