  • Peterson, Frank L (Water Resources Research Center, University of Hawaii at Manoa, 1974-02)
    In 1970, the Water Resources Research Center initiated a study of neutron well logging techniques in Hawaii. The primary objective of this study was to apply neutron logging techniques to the problem of obtaining reliable ...
  • Aoyama, Stephen S; Young, Reginald HF (Water Resources Research Center, University of Hawaii at Manoa, 1974-05)
    A field study was made between September 1972 to May 1973 to assess the water quality changes in Waiawa and Waimano Streams, particularly the effect of chlorinated effluent from the Pacific Palisades Sewage Treatment Plant ...
  • 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 ...
  • Fullerton, Charles M; Wilson, SK (Water Resources Research Center, University of Hawaii at Manoa, 1974-08)
    A computer monitored network of rapid response Raymond-Wilson rainfall intensity gauges has been established at the Cloud Physics Observatory (CPO), on the windward coast of the island of Hawaii, to record the passage of ...

    An investigation of recycling sewage effluent by irrigation under Hawaiian conditions is being conducted in pilot field studies near Mililani Town in central Oahu under the sponsorship of the Board of Water Supply and the ...
  • 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 ...
  • Peterson, Frank L; Sehgal, Man Mohan (Water Resources Research Center, University of Hawaii at Manoa, 1974-08)
    Neutron count data for calibration purposes were collected by neutron logging in 4 boreholes, and porosity data were determined from photo logs run on the same 4 boreholes. A neutron count-porosity calibration curve was ...
  • Liang, Tung; Huang, Wen-Yuan; Wu, I-Pai (Water Resources Research Center, University of Hawaii at Manoa, 1974-07)
    Planning an optimal system of activities for generating economic goods and services within an existing natural resource capacity is a difficult problem to solve. A mathematical programming model with the capacity to check ...
  • Nomura, Myron M; Young, Reginald HF (Water Resources Research Center, University of Hawaii at Manoa, 1974-09)
    Heavy metals have long been known to exert toxic effects upon plants and animals at all trophic levels. Through the use of water as a cleansing and transporting agent, various types and forms of metals find their way into ...
  • Liang, Tung; Yang, Kwang-Ping; Wu, I-Pai (Water Resources Research Center, University of Hawaii at Manoa, 1974-09)
    A computation technique based on the dynamic programming approach using the interactive Fortran language has been developed. The computerized design procedure can be used to obtain optimal design for single source water ...
