  • Koizumi, Melvin K; Burbank, Nathan C; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1966-08)
    This study investigated conditions contributing to cesspool failure and followed selected parameters to measure the degree of treatment afforded sewage in cesspool disposal. This laboratory study utilized bench scale soil ...
  • Young, Reginald HF; Lau, Stephen L; Burbank, Nathan C Jr (Water Resources Research Center, University of Hawaii at Manoa, 1967-01)
    A laboratory study was undertaken to determine the ability of four Oahu soils, Lolekaa, Lahaina, Manana, and Wahiawa, to remove ammonia, ABS, and coliforms from water percolating continuously through saturated soils. The ...
  • Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1967-02)
    A theoretical equation was adapted and modified for a water-table aquifer to relate freshwater flow to the sea, geometry of the fresh water-sea water interface, and aquifer characteristics under dynamic equilibrium. ...
  • Cox, Doak C; Lao, Chester (Water Resources Research Center, University of Hawaii at Manoa, 1967-03)
    Two deep wells, one at Puuloa and the other at Ewa Beach in the Pearl Harbor area were drilled through the thick sedimentary gap into Koolau basalt, and have been readied for multiple-zone recording of water levels and ...
  • Kumagai, James S (Water Resources Research Center, University of Hawaii at Manoa, 1967-04)
    A critical appraisal of the extant literature was made to evaluate the various studies and concepts derived from these studies pertinent to groundwater recharge with respect to treatment, transport, and storage of recharge ...
  • Palmer, Leonard A (Water Resources Research Center, University of Hawaii at Manoa, 1967-04)
    This study developed instrumentation and techniques to be used for seismic exploration of groundwater in Hawaii. A three-stage field test of instruments and methods was conducted to determine their capability of recording ...
  • Kumagai, James S (Water Resources Research Center, University of Hawaii at Manoa, 1967-06)
    The laboratory study of the infiltration and percolation of sulfides and sewage carbonaceous matter was conducted in two phases: Phase I utilized simulated cesspool lysimeters and Phase II considered the generation of ...
  • Jiracek, George R (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    The reported high values of resistivity in the near surface zones in semi-arid regions on the island of Hawaii motivated research into the feasibility of using radio waves to sound the depth to the ground water table. Field ...
  • Joziasse, Cornelius; Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    Seismic recording and playback techniques and equipment are being developed for use in mapping small scale geologic structures of significance in controlling the movement of ground water. High-frequency seismic waves ...
  • Ekern, Paul C (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    The marine sub-tropic climate of Hawaii is particularly suited to the use of semi-contained hydraulic lysimeters. Field experiences in the use of these lysimeters reveal a number of problems among which were factors related ...
  • Burbank, Nathan C Jr; Chan, Po Lau; Young, Reginald HF (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    The waters of the streams in the South Kohala district of the island of Hawaii have long been noted for their extremely high color and at times a distinct peaty taste. Early attempts to treat this water have led to the ...
  • Ishizaki, Kenneth; Burbank, Nathan C Jr; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    The source of most of Oahu's domestic water supply is from ground water occurring in the permeable materials of volcanic rock. Movement of the ground water is intrinsically through thin cracks in basaltic lavas. This ...
  • Lepley, Larry K; Palmer, Leonard A (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    Two remote sensing techniques of measuring offshore ground-water spring discharge that have been studied are: (i) multispectral photography, and (ii) infrared thermometry. During the summer of 1967, exposure factors for ...
  • Von Seggern, David; Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    A portable, electromagnetic loop-coupling device has been built to locate points on the earth's surface over points in an underground cavity and to determine the depth to the cavity. This method presently requires both an ...
  • Gundersen, K R; Stroupe, D B (Water Resources Research Center, University of Hawaii at Manoa, 1967-12)
    From June through August 1967, a thorough investigation was made of the presence and numbers of coliform bacteria, fecal streptococci (enterococci), and bacteria capable of growing on peptone-seawater agar at 28°. Six ...
  • Wu, I-Pai (Water Resources Research Center, University of Hawaii at Manoa, 1967-12)
    Basic hydrological data including rainfall, runoff, historical flood, watershed characteristics, soil type, and land use of Hawaiian small watersheds on Oahu have been compiled and analyzed. Frequency analysis for annual ...
  • Lao, Chester; Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1968-04)
    On the basis of hydrology, geology, soils, and water quality, potential ground-water development along the coastal area of the Kahua area in the North Kohala District appears unfavorable for large supplies of fresh water. ...
  • Tanimoto, Richard M; Burbank, Nathan C Jr; Young, Reginald HF; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1968-06)
    A laboratory study was made of the ability of three Oahu soils, Wahiawa, Lahaina, (both Low Humic Latosols), and Tantalus cinder (of the ashy cindery isothermic family of Typic Dystrandepts) to remove the coliphage T4Br(II) ...
  • Lau, L Stephen; Hailu, Tsegaye (Water Resources Research Center, University of Hawaii at Manoa, 1968-11)
    All known tritium measurements made of Hawaii rainwater, ocean water, surface water, and ground water are summarized. Ocean water yielded 10 to 20 T.U. in 1963-65. Tritium in rainwater rose from a low 6 T.U. in 1961 to a ...
  • Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1968-11)
    In order to locate the relatively optimum sites for drilling exploratory holes for fresh water, an electrical resistivity survey was conducted along the new Mahukona-Kawaihae Road on the west flank of the Kohala Mountain. ...
