ISSUES AND OTHER INFORMATION: The RSM program goals are development of tools and knowledge necessary to understand the effects of sediment management actions at both local and regional scales. The program is managed by the Engineer Research and Development Center (ERDC), which is part of the U.S. Army Corps of Engineers. The southeast coast of O'ahu, Hawai'i is an excellent site to determine the nature of random loss/gain of sand, shoreline recession/accretion and the general nature of littoral transport considering the important recreation and economic impact to the area.
RECOMMENDED IMPLEMENTATION PLAN FOR ADDED WORK: Funds would be used to initiate coastal engineering investigations and computer modeling for this study to (1) document long-term trends in wave climate, (2) develop a regional sediment budget and a Geographic Information System (GIS) for three interconnected littoral cells within the region, (3) identify suitable sand sources, and (4) develop/calibrate a sediment transport model for the southeast coast of O'ahu, Hawai'i. Contingent upon the full funding of this three year study effort, final products are to include a sand source inventory, regional sediment management plan, and a web-enabled GIS platform for the Southeast O'ahu Region, Hawai'i.
