  • Eto, Marshall A; Burbank, Nathan C Jr; Klemmer, Howard W; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1967-08)
    This study investigated the ability of two Oahu soils, Wahiawa and Lahaina, to prevent chlorinated hydrocarbon pesticides; DDT and Lindane, in acetone solutions from percolating through the soils. The study was prompted ...
  • Adams, William M; Peterson, Frank L; Mathur, Surendra P; Lepley, LarryK; Warren, Clifton; Huber, Richie D (Water Resources Research Center, University of Hawaii at Manoa, 1969-09)
    Several geophysical surveys have been conducted over the coastline area between Kawaihae and Kailua-Kona for the purpose of locating the optimum sites for possible development of ground water from the basal lens. A low-level ...
  • Tenorio, Pedro A; Young, Reginald HF; Whitehead, H Collins (Water Resources Research Center, University of Hawaii at Manoa, 1969-10)
    A joint research effort was undertaken by the Water Resources Research Center and the Honolulu Board of Water Supply to investigate the physical and chemical characteristics of irrigation return water in Pearl Harbor-Waipahu, ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1972-09)
    The nature and results of the first year of experimental and evaluative work of the Coastal Water Quality project of the University of Hawaii's Sea Grant Program are summarized in this report. The project is a multi-directional, ...
  • Hufen, Theodorus H; Buddemeier, Robert W; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1973-05)
    Water samples collected from various surface and sub-surface sources on the island of Oahu were analyzed for tritium levels. Tritium activity levels in twenty-five monthly rainwater samples show a seasonal dependence with ...
  • Matsushita, Gordon K; Young, Reginald HF (Water Resources Research Center, University of Hawaii at Manoa, 1973-06)
    The purpose of this study was to determine the changes in stream water quality related to variations in land use patterns and to establish some baseline data for assessing the Hawaii State Water Quality Standards for surface ...
  • Williams John A; Liu, Ta-Chiang (Water Resources Research Center, University of Hawaii at Manoa, 1973-07)
    A system of two isotropic and homogeneous infinite aquifers, which are separated by an aquitard and subject to tidal fluctuations along their coastal boundary, has been analyzed and a mathematical model has been developed ...
  • Fullerton, Charles M; Raymond, David J (Water Resources Research Center, University of Hawaii at Manoa, 1973-07)
    Two instruments have been used to measure the rate of rainfall from tropical clouds over the windward coast of the Island of Hawaii. The Workman intensity gauge employs strain gauges to sense the deflection in a movable ...
  • Adams, William M; Huber, Richie D (Water Resources Research Center, University of Hawaii at Manoa, 1973-07)
    For a proposed reforestation of the canyon country of east Lanai, seedlings will be required. The seedlings could be grown in east Lanai, preventing the stress of transplantation from a different environment, if an adequate ...
  • Williams, John A; Soroos, Ronald L (Water Resources Research Center, University of Hawaii at Manoa, 1973-07)
    Pumping test data from eight locations including the islands of Oahu, Maui, and Molokai were selected and analyzed. The test data were selected on the basis of completeness, reliability, and aquifer type and boundary ...
  • Cheng, Edmond DH; Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1973-08)
    Monthly rainfall data of several stations in Kalihi Basin, Manoa Basin, and Kaneohe Area, all on Oahu, and the central sloping area of Molokai were correlated to watershed parameters of the areas. Distance measured from ...
  • Shamey, Louis J; Adams, William M (Water Resources Research Center, University of Hawaii at Manoa, 1973-09)
    To facilitate the interpretation of geophysical electrical well logging data, the apparent resistivity has been calculated in a model in which the experimental situation is approximated by three coaxial cylindrical zones ...
  • Lau, L Stephen (Water Resources Research Center, University of Hawaii at Manoa, 1973-09)
    This report summarizes the results of the second year of investigative and evaluative work of the University of Hawaii's Sea Grant Program project, "Quality of Coastal Waters" The general objectives of this multidisciplinary ...
  • Fok, Yu-Si (Water Resources Research Center, University of Hawaii at Manoa, 1973-10)
