Abstract: The US Army Engineer Waterways Experiment Station Coastal Engineering Research Center was requested by the US Army Engineer District, Alaska (CENPA) to provide technical assistance in engineering analysis and assessment of various structure alternatives for flood mitigation and erosion control at the southeast coastline of Homer Spit, Alaska. Study elements included are Have climatology and omveve transformation analysis, coastal geomorphological study, tidal circulation analysis, shoreline change numerical modeling analysis, and structure elements design. This report details the study and provides final recommendations to CENPA. Spectrally-based deep-water wave heights, peak periods, and peak directions were calculated from Homer Spit wind distributions based on the usable wind data of February 1965 to February 1986. The deep water wave statistics were then transformed by applying the Regional Coastal Processes Wave finite difference model to the breaking points near the Spit shoreline as the data base for nearshore sediment transport analysis. TI1e shoreline response to various structure alternatives was analyzed by using the shoreline change model. Five options--including without project, revetment extension, revetment extension with beach fill, beach fill, and offshore breakwater--with various design alternatives were simulated by the modeling study. The final recommendations were formulated based on the model simulation results along with engineering judgments derived from the other study elements of the project.
