NEOWAVE Regional Tsunami Model: Hawaii: Kauai: Port Allen

Non-hydrostatic Evolution of Ocean WAVEs (NEOWAVE) regional tsunami model for Port Allen on the southwest coast of the island of Kauai in the state of Hawaii, categorized by earthquake magnitude and subduction zone. Includes nearshore hazard maps of surge, drawdown, and current for hypothetical advisory and warning-level tsunamis from potential sources at the Aleutian, Kuril-Kamchatka, and Peru-Chile subduction zones. Data are gridded at approximately 9-m resolution referenced to the WGS84 coordinate system and use a vertical datum of mean sea level (MSL). This shock-capturing, dispersive wave model computes tsunami generation, propagation, and inundation for complex flow patterns in shelf and reef environments. It has been validated with analytical, laboratory, and field benchmarks and is approved by the National Tsunami Hazard Mitigation Program. These hazard maps cover tsunamis only; other potential hazards such as wind waves and swells would be additive to the surge, drawdown, and current described by these data.
