1996年1月1日 · Southern Oahu is divided into six areas, Ewa, Pearl Harbor, Moanalua, Kalihi, Beretania, and Kaimuki. Southeastern Oahu is divided into the Waialae and Wailupe-Hawaii Kai areas. Along the northeast coast of windward Oahu is the Kahuku ground-water area. The aquifers of Oahu contain shallow freshwater and deeper saltwater flow systems.

This first report provides Aquifer Codes and Status Codes for the island of 0’ahu. The Aquifer Codes incorporate locational and descriptive indices, while the Status Codes indicate the developability, utility, quality, uniqueness and vulnerability to contamination of …

Volcanic rocks ranging in age from Pliocene to Holocene, make up most of Oahu and compose the most important aquifers. Quaternary-age consolidated sedimentary deposits, which are principally coralline limestone, form productive aquifers in lowlands and nearshore areas but generally contain brackish water or saltwater.

2014年4月9日 · Description: Aquifers determined/defined by the Hawaii State Dept. of Health. (Note: DLNR maintains another version of aquifers, which is more administrative in nature, and which has different boundaries than the DOH version, which is more resource-oriented in nature).

Hawaii Aquifers as determined/defined by DLNR.

2023年7月7日 · The volcanic aquifers of the Hawaiian Islands supply water to 1.46 million residents, diverse industries, and a large component of the U.S. military in the Pacific. Groundwater also supplies fresh water that supports ecosystems in streams and near the coast.

Groundwater occurrence and movement in Hawai‘i’s volcanic aquifers can be described in terms of four conceptual models: (1) fresh groundwater lenses in high-permeability lava-flow aquifers, (2) aquifers with groundwater impounded by dikes, (3) thickly saturated low-permeability aquifers, and (4) perched aquifers.

The aquifers of Oahu contain two flow regimes: shallow freshwater and deep saltwater. The freshwater floats on underlying saltwater in a condition of buoyant displacement, although the relation is not necessarily a simple hydrostatic balance everywhere. Natural driving mechanisms for freshwater and saltwater flow differ.

Although Hawaii aquifers are vastly heterogeneous, Oahu’s hydrogeologic framework can be simplified to three hydrogeologic units: (1) dike-intruded volcanic rock, (2) dike-free volcanic rock, and (3)

1991年1月1日 · The water supply for the population of the island of Oahu, Hawaii is obtained primarily from ground-water sources, recharged by the infiltration of rainfall and irrigation water. The importance and limited nature of these sources caused the island of Oahu to be selected, along with 27 other aquifer systems in the United States, as part of the U ...
