Waves, erosion, spray, and storm surge were recorded at Tarsiut Island during the open water season of 1982. This paper analyzes data collected and compares findings of the program to assumptions made during the design of Tarsiut Island. Waves experienced at Tarsuit in 1982 were more severe than normal and more severe than were used in design of the berm. Wave interaction with the berm and caisson was confirmed to agree well with theory and design except for elevation +10 m where horizontal forces were greater than theory would indicate. Tarsiut berm was identified as being stable and subject to considerably less erosion than was assumed in design. Wave spray data was collected by monitoring infilling of 45 gallon drums during wave spray events. Intensity of spray on the island surface was found to be as high as 102 cm/hr but this rate was not typical. Spray intensity was found to reduce with distance in from the caisson wall by a negative exponential relationship. Storm surge was identified to exist at Tarsiut and a maximum of 0.2 m positive and 0.2 m negative surge were measured. Indications are that surge is related to storm direction as well as wind speed.
