Popis:	Increasing demands on coastal areas require enhanced understanding of coastal erosion hazards. Here we analyze a 5-km segment of the Kihei coastline (Maui, Hawaii) centered on an area of chronic coastal erosion. A high-resolution database of variations in shoreline sediment volume over the past century reveals a complex and dramatic pattern of changes between 1900 and 1997. Comparisons of historical sediment erosion and accretion at barriers to longshore transport are used to estimate longshore sediment fluxes over this period. In the absence of detailed long-term oceanographic and meteorological data for the site, fluctuations in the magnitude and direction of net longshore sediment transport (NLST) are a potentially valuable resource for investigating why documented changes have occurred. Available data suggest that observed patterns of NLST reflect multidecadal variations in Kona storm (strong, rain-bearing winds from the southwest) activity. These storms appear to be modulated by the Pacific ...
