Keeping up with the coast: quantifying shoreline change on Hawaiʻi Island

May 10, 2018 7:00 PM

A Maunakea Speaker Series presentation by Rose Hart, UH Hilo


The next scheduled program in the Maunakea Speaker Series will be held Thursday 10 May, 2018 at UH Hilo Science & Technology Building (STB) Room # 108. This exciting free lecture is open to the public and starts at 7 pm.

Hawaiʻi Island's coastal communities face many challenges in adapting to the impacts of sea-level rise, coastal erosion, and subsidence. To better predict and manage coastal vulnerabilities, this research effort quantified shoreline change rates from the present and recent past for three different coastal settings on Hawaiʻi Island. Shoreline change was quantified at Hāpuna State Beach Park, Honoliʻi sea cliff, and Kapoho Tide Pools/Hawaiian Vacation Lands using shoreline records from historic aerial photographs and elevation datasets collected from small unmanned aerial systems (sUAS or drones). These data were merged with sea-level rise and subsidence projections to estimate and visualize vulnerabilities. Results from this study provide insights to the chronic, seasonal, and episodic coastal processes that threaten communities and resources along Hawaiʻi Island's coast and help Hawaiʻi County planners improve coastal management strategies.

Rose Hart is a M.S. candidate of the University of Hawaii at Hilo's Tropical Conservation Biology and Environmental Science program. She has spent the last two years researching coastal vulnerabilities on Hawaiʻi Island and identifying strategies for building coastal resilience through adaptive planning. When she is not working, she enjoys spending time outdoors and exploring the beauty of the Big Island.

Parking is open and available without charge after 4:00 pm.


About the Maunakea Speaker Series 

The Maunakea Speaker Series is a monthly scholar-focused presentation offered as a partnership among the Office of Maunakea Management, 'Imiloa Astronomy Center, and the University of Hawai'i at Hilo Department of Physics & Astronomy. This collaborative venture gives the community unprecedented access to fascinating research taking place on Maunakea and other topics unique to the Island of Hawai'i. A venue for scholars to share their stories and learn from discussion, the series promotes understanding and collaboration across all sectors of the community, while addressing the goals of the University of Hawai'i at Hilo.
