This project snapshot provides a brief overview of the project "Diagnosing and Communicating the Effect of Climate Variability on Frequency of Coastal Inundation".
Project researchers are measuring impacts of sea level variability on coastal reefs and communities. Researchers will relate Pacific climate extremes to local impacts, such as coastal flooding, that matter to residents and resource managers inundation by waves. This handout gives a quick overview of the project methods.
In recent years, rising sea levels have threatened critical infrastructure and cultural assets at Puʻuhonua o Hōnaunau National Historical Park thus motivating the park to make adaptive decisions in managing these key resources. To support the development of decision support tools for sea level rise preparedness, the U.S. Geological Survey (USGS) Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for Puʻuhonua o Hōnaunau National Historical Park. This dataset was developed in collaboration with the University of Hawaii- Mānoa Sea Level Center, Department of Interior Pacific Island Climate Adaptation Science Center, and...
This tool provides projections and analysis of high-tide flooding days at the locations of tide gauges. If a tide gauge does not exist at the desired location, analysis from the closest tide gauge can provide useful information. However, it is important to consider the potential impact of local factors that can differ even over short distances such as land subsidence. You can select a location in two ways: Select a location from from the dropdown menu displaying the current location name. The locations can be searched by typing in this field. Select a location by clicking on the map. Note that the map can be hidden once the desired location is chosen using the switch beneath the location name. The methodology...
Increased coastal flooding due to sea-level rise (SLR) threatens the culture, habitat, and essential infrastructure of the Hawaiian and U.S. Affiliated Pacific Islands. The purpose of this project was to respond to the needs of Pacific Island communities for improved information about the frequency of coastal flooding—both in the near term and throughout the 21st century. Seasonal sea-level and flooding forecasts were produced by combining multiple types of information into a single forecast that performs better out to six months than any individual forecast. The forecasts are provided on a website created for this project. Projections of tidal flooding for the 21st century were produced for 35 island locations...
U.S. Geological Survey (USGS) and University of Hawaii - Mānoa (UH) scientists conducted field data collection efforts from August 19th - 27th, 2019 at Pu‘uhonua O Hōnaunau National Historical Park on the Big Island of Hawaii. The data collection efforts utilized a combination of remote sensing technologies to map the topography, critical infrastructure, and most importantly, the cultural assets of Pu‘uhonua O Hōnaunau National Historical Park. The USGS and UH team collected Global Navigation Satellite System (GNSS), total station, and ground based lidar (GBL) data, along with utilizing Uncrewed Aerial Systems (UAS) to collect imagery and UAS lidar to map these features. This data release contains shapefiles of...
Sea level anomaly extremes impact tropical Pacific islands, often with too little warning to mitigate risks. By compiling monthly sea level anomaly predictions from multiple statistical and dynamical (coupled ocean-atmosphere) models, which are typically skillful out to at least 6 months in the tropical Pacific, improved future outlooks are achieved. We deliver an experimental real-time forecast of monthly mean sea level anomalies and information that can be used to reduce impacts associated with sea level extremes. This product provides an outlook of monthly sea level anomalies for the next one to two seasons. We combine sea level forecasts with astronomical tide predictions to provide more accurate predictions...
This document contains planning materials for Pu‘uhonua O Hōnaunau National Historical Park (PUHO; an important Hawaiian cultural site) to address information gaps in sea level rise planning materials. This report focuses on planning horizons of 10-30 years and also provides information about the entire 21st century. Specific assets in the park are addressed and local/park knowledge was used to assess the level and frequency at which the any given structure can be inundated and still maintain its integrity.
Abstract (from http://journals.ametsoc.org/doi/abs/10.1175/JAMC-D-16-0284.1): Sea level anomaly extremes impact tropical Pacific Ocean islands, often with too little warning to mitigate risks. With El Niño, such as the strong 2015/16 event, comes weaker trade winds and mean sea level drops exceeding 30 cm in the western Pacific that expose shallow-water ecosystems at low tides. Nearly opposite climate conditions accompany La Niña events, which cause sea level high stands (10–20 cm) and result in more frequent tide- and storm-related inundations that threaten coastlines. In the past, these effects have been exacerbated by decadal sea level variability, as well as continuing global sea level rise. Climate models,...
