Regional Sediment Budgets for the Haleiwa Region, Oahu, Hawaii

Abstract : This Coastal and Hydraulics Engineering Technical Note (CHETN) reviews the development of conceptual regional sediment budgets (RSB) for the Haleiwa Region on the island of Oahu, Hawaii, as part of the Hawaii Regional Sediment Management (RSM) Program. This document discusses the methodology used for determining volume change rates as well as numerical models utilized, including the Particle Tracking Model (PTM), in support of identifying sediment pathways in the region. The results of these investigations were used to create the pre- (1922 1948) and post-Haleiwa Harbor (1988 2006) sediment budgets for the Haleiwa Region using the Sediment Budget Analysis System (SBAS) software.
