  • Hori, Daniel H; Burbank, Nathan C Jr; Young, Reginald HF; Lau, L Stephen; Klemmer, Howard W (Water Resources Research Center, University of Hawaii at Manoa, 1970-01)
    A laboratory study was made to determine the ability of three Oahu soils, Wahiawa, Lahaina, (both Low Humic Latosols), and Tantalus cinder to prevent possible contamination of the basal-water lens by the passage of virus. ...
  • Ekern, Paul C (Water Resources Research Center, University of Hawaii at Manoa, 1970-07)
    Water use by sprinkler irrigated sugarcane under flat-bed culture was measured in four 100 ft 2 by 5 ft deep hydraulically weighed lysimeters at the Kunia substation of the Hawaiian Sugar Planters' Association. Nine-week-old ...
  • Burbank, Nathan C Jr; Chan, Po Lau; Young, Reginald HF (Water Resources Research Center, University of Hawaii at Manoa, 1970-03)
    The waters of the streams in the South Kohala District on the island of Hawaii have long been noted for their extreme high color and at times a distinct peaty taste. Early attempts to treat this water have led to the ...
  • Williams, John A; Wada, Ronald N; Wang, Ru-Yih (Water Resources Research Center, University of Hawaii at Manoa, 1970-05)
    This report presents the results of a model study on the propagation of periodic fluctuations in the piezometric head through a saturated porous media. Three different models were employed: a hydraulic model, a mathematical ...
  • 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. ...
  • Nunogawa, Jerry H; Burbank, Nathan C Jr; Young, Reginald HF; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1970-08)
    This study determined the 24, 48, 96-hour median tolerance limit of phenol, DDT, dieldrin, and lindane of five species of fish commonly found in streams and estuaries in semi-tropical areas. They are: (i) Gambusia affinis ...
  • Lau, L Stephen; Chou, James CS (Water Resources Research Center, University of Hawaii at Manoa, 1970-07)
    A field study was made to evaluate the applicability and problems of desalting brackish ground water from basaltic and reef limestone aquifers in Honolulu, Hawaii with the electrodialysis process. The three-week study ...
  • Wang, Ru-Yih; Wu, I-Pai; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1970-08)
    The analysis of about 240 flood hydrographs of 29 small watersheds on the island of Oahu, Hawaii, shows some unique hydrologic characteristics. A typical Hawaiian small watershed has a small area, flash peak, short time ...
  • Hargis, David R; Peterson, Frank L (Water Resources Research Center, University of Hawaii at Manoa, 1970-10)
    In July of 1969 the Water Resources Research Center began an investigation of artificial recharge practices in Hawaii. The objectives of this study were: (i) to compile all sites in the State where artificial recharge has ...
  • Tenorio, Pedro A; Young, Reginald HF; Burbank, Nathan C Jr; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1970-12)
    This study continued the joint research effort undertaken by the Water Resources Research Center and the Honolulu Board of Water Supply in 1967 to investigate the physical and chemical characteristics of irrigation return ...
  • Huber, Richie D; Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1971-02)
    The gravity method has been applied in three wells in Hawaii to estimate density and porosity logs. The wells are the Schofield shaft on the island of Oahu, the Kihei #3 shaft on the island of Maui and the Pahala shaft on ...
  • Shamey, L J; Adams, W M (Water Resources Research Center, University of Hawaii at Manoa, 1971-03)
    A two-zone theoretical model, consisting of a cylindrical borehole filled with drilling mud and surrounded by homogeneous, isotropic rock, was studied to aid interpretation of electrical resistivity logs. Apparent resistivities ...
  • Lau, L Stephen; Mink, John F; Loo, Chester (Water Resources Research Center, University of Hawaii at Manoa, 1971-05)
    A 200 square kilometer representative area of the coastal plain of southwestern Taiwan was selected for a cooperative pilot ground-water study to identify and provide methods and knowledge that are essential and appropriate ...
  • Lepley, Larry K; Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1971-05)
    A new geophysical technique for the remote measurement of the electromagnetic properties of natural surfaces was investigated. Theoretical and laboratory work has produced evidence for the validity of the use of ultra-high ...
  • Chou, James CS (Water Resources Research Center, University of Hawaii at Manoa, 1971-07)
    The interpolation formulae for vapor pressures, specific volumes, enthalpies and heats of vaporization of ordinary seawater have been determined in the temperature range 0° to 200°C for salinities of 0 to 120 pot, based ...
  • 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 ...
  • Pfund, Rose T; Steller, Dorothy L (Water Resources Research Center, University of Hawaii at Manoa, 1971-07)
    Pertinent to the field of the water resources of the Hawaiian Islands there have been several previous bibliographies, but they are mostly out of date, and there are great gaps among their coverages. The need for a ...
  • Williams, John A; Liu, Ta-Chiang (Water Resources Research Center, University of Hawaii at Manoa, 1971-11)
    Mathematical and electric analog (R-C circuit) models for two one-dimensional non-homogeneous coastal aquifers have been developed. The first is a semi-infinite aquifer having a discontinuous change in permeability at a ...
  • Chen, Jeong-rong; Young, Reginald HF (Water Resources Research Center, University of Hawaii at Manoa, 1971-09)
    Characteristics and treatment efficiency of the sludge digestion facilities at four sewage treatment plants of the City and County of Honolulu, one each at Kaneohe, Kailua (both secondary treatment-trickling filter plants), ...
  • Hufen, Theodorus H; Buddemeier, Robert W; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1971-11)
    A field investigation was undertaken to establish the present tritium and radiocarbon activity levels of natural waters found in various parts of the island of Oahu. The instrumentation required for the radiocarbon analysis ...
