The Anahola study area (transects 45 – 174) is located on the east coast of Kauaʻi. The area is bounded by Aliomanu Beach to the north and Kahala Point to the south. The shoreline is composed of calcareous sand beach interrupted by basalt headlands with a fringing reef offshore. Overall, the area is stable to slightly eroding with an average shoreline change rate of -0.1 ft/yr. The area lends itself to division into three portions. Aliomanu Beach (transects 45 – 88) is located to the north of Kuaehu Point. This section of the study area is experiencing slight to moderate erosion with an average shoreline change rate of -0.3 ft/yr. Anahola Beach (transects 89 – 128) to the north of Anahola River has experienced slight erosion with an average shoreline change rate of -0.2 ft/yr. Anahola Beach Park (transects 129 – 174) to the south of Anahola River has experienced slight accretion with an average shoreline change rate of 0.1 ft/yr. Previous studies* found similar trends in shoreline change for the Anahola study area shoreline.
