Water resources of southeastern Oahu, Hawaii

Summary of the Oahu, Hawaii, Regional Aquifer-System Analysis

“…The Waialae and Wailupe-Hawaii Kai ground-water areas ( fig. 95) are separated by a poorly defined zone of northeast-trending dikes (Takasaki and Mink, 1982). Numerous dikes within the Kaau rift zone ( fig.…”

“…The effects of increased pumping from the Schofield area were evaluated by Dale and Takasaki (1976). Finally, the water resources of southeastern Oahu were described by Takasaki and Mink (1982). Dike-impounded ground water and the effects of tunnels used to develop this ground-water source in windward Oahu have been described and discussed by Hirashima (1971) and Takasaki and Mink (1985).…”

Geohydrology and numerical simulation of the ground-water flow system of Kona, Island of Hawaii

“…Coarse deposits, such as cinder, are generally more permeable than fine ash. Takasaki and Mink (1982) estimated that the hydraulic conductivity of pyroclastic deposits of southeast Oahu generally ranges from 1 to 500 ft/d. No estimates are available for the hydraulic conductivity of pyroclastic deposits in the Kona area.…”

Ground-water resources in Kaloko-Honokohau National Historical Park, Island of Hawaii, and numerical simulation of the effects of ground-water withdrawals

“…Coarse deposits, such as cinder, are generally more permeable than fine ash. Takasaki and Mink (1982) estimated that the hydraulic conductivity of pyroclastic deposits of southeast Oahu generally ranges from 1 to 500 ft/d. No estimates are available for the hydraulic conductivity of pyroclastic deposits of western Hawaii.…”
