Abstract: Shinnecock Inlet is the easternmost of six coastal inlet which bracket the barrier island on the south shore of Long Island, New York. Through recent history, Shinnecock Inlet has exhibited dynamic changes, forming and closing from 1770 to 1938. After the hurricane of 1938, the inlet was permanently opened due to the structural stabilization works constructed by local interests. In the 1980's, shoaling in and fronting the inlet caused dangerous navigation through the channel, especially for the fleet of the local fishing cooperative. Due to the dynamic regime, the jetties constructed by local interests began a rapid deterioration. A Federal project, which takes a systems approach to the project area, was approved in 1988. The project includes a navigation channel, sedimentation basin, rehabilitation of the jetties and bayshore revetment, and a system of sand by-passing. Construction of the inlet improvements were initiated in 1990.
