Living Beaches talk explains Kauai’s shorelines

KAPAA — Kauai geologist, researcher and sedimentology specialist Chuck Blay will be presenting “Understanding our Living Beaches,” a free talk on Kauai’s beaches at the Kapaa Library at 2 p.m. Saturday.

Blay has been investigating Kauai’s beaches for more than 30 years, and the talk will provide a general understanding of the formation and evolution of beaches, as well as the changes they undergo from both natural and human influences.

“Blay will review much of his comprehensive work on our extremely dynamic Westside beaches and promote the need to investigate in greater detail the prominent east side beaches such as those all along the Kapa‘a-Wailua coastal zone, many of which are under the stress of human development,” according to a press release.

At 5 million years of age, the geologically mature island of Kauai has a coastline of more than 50 distinct sandy beaches. These beaches total 52.5 miles in length – nearly half of Kauai’s perimeter, the release said. That perimeter was mapped by Blay in the mid-1980s, a project which he did mostly on foot in order to better understand the origins of the shoreline’s geologic features.

A portion of the meeting will also include W-KNA board elections and an update on W-KNA’s contested case regarding the proposed setback for the county shared use path along Waipouli Beach.
