Possible sand resources on the reef front around Oahu

Large sediment deposits on the reef front around Oahu are a possible resource for replenishing eroded beaches. An overview is given on the collection of closely spaced, high-resolution subbottom profiles that clearly depict the deposits in three areas, namely, the Kailua Bay off the windward coast, Makua to Kahe Point off the leeward coast, and Camp Erdman to Waimea off the north coast.
