Abstract:

Homer Spit is a natural spit formed by littoral processes at the confluence of Kachemak Bay and Cook Inlet in Southcentral Alaska, some 192 km southwest of Anchorage. The immediate erosion problem is the continual storm damage to a section of the State-maintained roadway along the southwestern shore of the spit. The State of Alaska has attempted to control erosion in the affected area through the use of wooden beach groins, wooden bulkheads, a section of sheet piling, and a concrete slab revetment. To date, all of the methods have failed. Several alternative solutions were formulated as a result of a 1985 reconnaissance study performed by the U. S. Army Corps of Engineers, Alaska District. Study components are discussed. It was concluded that beach erosion at Homer Spit is severe and requires a permanent solution.
