The Effects Of Sedimentation From Unpaved Roads On Coral Reefs: An Analysis Of St. John, Usvi And Koh Tao, Thailand, Dillon Vassallo

Geography and the Environment Capstone Projects

As the tourism industry drastically expanded on St. John, US Virgin Islands, developers constructed hundreds of unpaved dirt roads to facilitate the fast-paced population growth on the island. During rain storms, the unpaved roads created runoff from the mountainous terrain of St. John, and sedimentation smothered the coral reefs surrounding the island. Due to the geography of the island, coral reef characteristics, and dirt road network, the biggest threats to coral reefs around the island was considered sedimentation from unpaved roads. Sedimentation drastically threatens the ability for reefs to survive. This study uses existing research on the sedimentation from unpaved …
