Abstract
We evaluate three classes of shoreline change rate methods on all sandy beaches of Maui: 1) methods that estimate shoreline change transect by transect, 2) methods that combine data from all transects to estimate shoreline change, and 3) extensions of (2) that include acceleration. Using these, we compare 50 yr hazard zones from beaches exposed to different conditions, natural beaches versus altered beaches, and well-defined littoral cells versus open systems. Acceleration methods fit the data well, but don't predict the erosion hazard zone well. Altered beaches and open system beaches are better fit by methods with acceleration at a higher proportion than natural or pocket beaches. The traditional transect by transect method that calculates shoreline change at discrete points along a beach never qualifies as the best fit model.
