  • A model to predict the bacterial quality of a rangeland stream

    Creator:
    Biskie, Howard A
    Abstract:
    Grazing cattle usually have access to streams as a source of drinking water. A model was developed for the personal computer to predict the bacterial quality of these streams. The model estimates the number of organisms that enter the stream by the direct deposit of feces and by runoff from...

  • Behavior of a compliant wave-current barrier

    Creator:
    Kerper, Dale R.
    Abstract:
    This study includes an analytical solution to the wave-current barrier interaction problem and large scale experiments to validate the theory. The boundary value problem is solved mathematically by characterizing the flow field and barrier motion separately, then coupling the relationships with the appropriate kinematic and dynamic boundary conditions. The flow...

  • Spatial and temporal characteristics of groundwater levels adjacent to beaver ponds in Oregon

    Creator:
    Sharps, Diana E.
    Abstract:
    This study was undertaken to evaluate the spatial and temporal characteristics of riparian groundwater tables adjacent to beaver ponds. The research was conducted in two parts; in the first portion a two-dimensional, finite-difference computer model was developed and utilized to simulate groundwater elevations through time in pond-adjacent aquifers. Two types...

  • Study of interfacial condensation in a nuclear reactor core makeup tank

    Creator:
    Ma, Chang Chun
    Abstract:
    Steam interfacial condensation in a core makeup tank was simulated using the code RELAP5/MOD3 version 8.0 to predict the violent pressure oscillation phenomena in a core makeup tank. Six base cases were carried out to study the effects of back pressure and of vacuum conditions produced in the core makeup...
