West Maui Wave Run-up Forecast Validation

Metadata Updated: October 14, 2022

The Pacific Islands Ocean Observing System (PacIOOS), University of Hawaii School of Ocean and Earth Science and Technology Department of Oceanography, and Hawaii Sea Grant are developing a high-resolution, real-time wave run-up forecast and notification system for West Maui's coastline. In order to validate the site-specific, short-term forecasts and to determine meaningful thresholds associated with each forecast domain, citizen scientists contribute crowd-sourced photographs by documenting the shoreline of West Maui during predicted wave run-up events. Photos, observations, date, time, location, and other metadata are submitted online in this free, publicy-accessible dataset.

Site-specific, short- and long-term forecasts, will strengthen West Maui's coastal community and economy by enhancing preparedness and response operations, and by informing future land use planning. A combination of high water levels and large wave swells can result in significant coastal erosion, damage to infrastructure and properties, and land-based sedimentation that impairs coastal water quality. The State of Hawaii has experienced an increase in wave plus tide-driven flooding in recent years, and these events are expected to grow in numbers and duration due to sea level rise and changing wave energies.
