Hilo Bay Water Circulation and Water Quality Study -APRIL 2009

In October 2004, the County of Hawaii requested planning assistance from the U.S. Army Corps of Engineers, Honolulu District to evaluate water circulation and apparent degraded water quality within Hilo Bay and identify potential solutions. In response, this study was initiated to collect field data and implement numerical modeling of circulation, wave transformation, and identify alternatives to improve water quality in Hilo Bay. The study investigates the feasibility of modifying the Hilo Harbor breakwater to increase water circulation within Hilo Harbor. Increased circulation could potentially provide corresponding improvements in water quality within the bay thereby providing a more suitable environment for recreation and a greater aesthetic enjoyment of the area.
