  • 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...

  • Mathematical model of a phytoplankton community in a nitrate limited environment

    Creator:
    Grenney, William J.
    Abstract:
    Mathematical modeling of phytoplankton populations based on laboratory observations provides increased understanding of the interaction among the environmental and biological mechanisms. influencing growth dynamics. Such fundamental understanding is necessary to estimate the impact of man-made perturbations on natural population. A three-compartment mathematical model was developed to represent a phytoplankton population...
