  • Modeling estuary pollution by computer simulation

    Creator:
    Grenney, William J.
    Abstract:
    A digital computer model was developed to simulate the time and space distribution of a dissolved pollutant in an estuary. The program is basically a one-dimensional finite-difference model, but two dimensions can be represented by attaching together several one-dimensional channels. The influence of convection, dispersion and decay are included in...

  • An evaluation of the oxygen resources in the lower Willamette River during a critical low flow period

    Creator:
    Kari, Earl Nyhus
    Abstract:
    The lower Willamette River, located between river mile 4.0 and 26.5, is the most seriously polluted section of the Willamette River Basin. Low dissolved oxygen concentrations of 2.0 to 3.0 mg/1 are observed annually in this section of the river due to the pollutional loads discharged into it. Waste discharges...
