The Princeville study area (transects 0 – 99) is located on the north coast of Kauaʻi. The shoreline is composed of calcareous sand beach with a fringing reef offshore.
Overall, the area is eroding with an average shoreline change rate of -0.3 ft/yr. The area lends itself to division into three portions. Kaweonui Beach (transects 0 – 4) is located on the east of Kaweonui Point. The area is experiencing slight erosion with an average shoreline change rate of -0.1 ft/yr. The central section of beach (transects 5 – 45) has experienced erosion with an average shoreline change rate of -0.3 ft/yr. Anini Beach (transects 46 – 99) is bounded by Anini Stream and Hohono Point. This section of the study area is experiencing erosion with an average shoreline change rate of -0.2 ft/yr. Previous studies* found similar trends in shoreline change for the Princeville study area.
