  • Influence of expansive soils on structures in the Eugene area

    Creator:
    Bonell, John Alexander
    Abstract:
    Expansive soils in Eugene, Oregon present a problem to residents, consultants, contractors, and the city government. During the years 1977 to 1979, the nature and extent of the problem was identified, including an outline of the local occurrence of expansive soils and possible engineering solutions to the most often encountered...

  • Evaluation of techniques for on-farm monitoring of percolation and irrigation system performance

    Creator:
    Louie, Michael J.
    Abstract:
    Efficient use of water in agricultural production involves accurate assessment and control of the quantity and spatial uniformity of excess percolation. Passive Capillary Samplers (PCAPS), which sample water from the vadose zone have shown potential to provide superior estimates of soil water flux compared to alternative methods. In a four-year...

  • A study of the coagulation of kraft effluent by sea water

    Creator:
    Andrews, Ben Neal
    Abstract:
    The coagulation of effluent from the kraft pulping and papermaking process was investigated. The amount of material coagulated from saline mixtures of the effluent is determined as a function of time, salinity, kraft effluent concentration, and mixture pH. Individual sources of salinity include sea water and several different solutions of...

  • Collection and analysis of evaporative flux data for various climates

    Creator:
    Katul, Gabriel
    Abstract:
    Daily evaporative flux and meteorological data from three sites were collected and analyzed. Analysis included evaluation of several reference evapotranspiration estimating methods which were theoretically based on distinct physical laws. The estimating methods included pan evaporation, energy-based Priestly-Taylor, and combination methods with and without biological adjustments. The data set represented...

  • In situ measurement of the benthal oxygen requirements of tidal flat deposits

    Creator:
    Crook, Gene Ray
    Abstract:
    In situ light and dark planktonic and benthal respirometers were used to measure the oxygen requirements of Yaquina estuary water and benthal deposits. Respirometer devices were constructed so that actual conditions of mixing could be simulated and benthal deposit disturbance would be minimized. A mathematical model of a benthal respirometer...

  • The effect of mixing on the oxygen uptake rate of estuarine bottom deposits

    Creator:
    Martin, Duane Collins
    Abstract:
    A study of the effect of mixing on the oxygen uptake rate of estuarine bottom deposits is presented. The method of study involved the mixing of samples of bottom deposits with the overlying water to result in concentrations of suspended matter in the same order as observed in the estuary....

  • Chetco River tidal hydrodynamics and associated marina flushing

    Creator:
    Tang, Shing Shirly
    Abstract:
    The purpose of this study was to provide an understanding of the interrelationships between fresh and salt water Circulation, tidal transport and flushing patterns in the Chetco River estuary and its boat basins. Field work and water quality measurements were conducted at the entrance of the Chetco River during 1975...

  • Airphoto analysis of estuarine circulation

    Creator:
    Weise, Harry Gordon
    Abstract:
    Aerial photography has become a valuable method of acquiring information on estuarine current circulation patterns. The method provides a comprehensive picture of nearly simultaneous surface water movements. It represents a significant improvement over conventional surface float and current meter methods because large areas may be covered in great detail with...
