COASTAL MODELING FOR REGIONAL SEDIMENT BUDGET IN WEST MAUI, HAWAII. (2017). Coastal Engineering Proceedings, 1(35), sediment.14. https://doi.org/10.9753/icce.v35.sediment.14

Abstract

The West Maui Region incorporates a thin coastal margin backed by steep mountainous terrain that has been vastly altered by agricultural and urbanized development. Coastline includes headlands and reefs with a very limited supply of sediment. Shoreline was found to be erosional chronically based on average rates. The dynamics of the area are complex with a wave climate affected by intricate bathymetry, wind, and island sheltering. Longshore currents vary locally and temporally from nearshore to offshore. Wave and current modeling indicates that large waves in the summer and winter have driven the majority of sediment transport along the coast. The littoral transport is essentially northward in summer and southward in winter. The net transport of longshore sediment is overall small. The nearshore eddy formation with wave breaking nearshore over narrow sandy bed and wide reefs may increase the complexity of sediment movement within the region.
