ECONOMIC VALUE OF BEACH AND DUNES SYSTEMS IN STORM PROTECTION, ISLE OF PALMS, SOUTH CAROLINA
As a response to cases like this one, the U.S. Army Corps of Engineers didn’t do many dune construction projects, instead using available sediment to focus on large berms, or long and flat beaches. As communities determine the amount of investment necessary to protect or rebuild their dunes, understanding the value they provide to their community will be paramount. Economic studies will also increase public awareness about their importance. This study focuses on Isle of Palms, South Carolina a well-documented island on the South Carolina shoreline with a typical, but varied, beach/dune system. The Wave Height Analysis for Flood Insurance Studies (WHAFIS) model is used to estimate wave crest elevations along representative transects using a one-dimensional model. This model is the basis for creating a better understanding of the protective value of Dunes in the region. The results of this study increase our understanding of dunes and their storm protection value as climate change and coastal development make scenario planning even more important in today’s decision making process.
