-
(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), ...
-
(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 ...
-
(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, ...
-
(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 ...
-
(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 ...
-
(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 ...
-
WRRCTR No. 68 Optimum Drilling Sites for Ground-Water Development on the East Coast of Lanai Island (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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1973-11)A study of the application of reverse osmosis technology to the treatment of Hawaiian low quality waters was conducted. The purpose of the study was to investigate the technical and economical feasibility of utilizing ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1973-10)The major tasks under Phase II of the project were to: (1) adapt and evaluate several existing watershed simulation models for their applicability under local conditions, (2) expand the data collection effort in the research ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(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 ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1974-12)The objectives of this study are to construct and analyze the patterns and trends of water demand in the service areas of the Honolulu Board of Water Supply, and to identify factors affecting water demand with the intent ...
-
(Water Resources Research Center, University of Hawaii at Manoa, 1975-03)Recent studies have demonstrated the important moisture contribution from fog precipitation in mountain areas on the island of Hawaii. The present study investigates research methodologies useful in the study of Hawaiian ...
