A steady state mathematical model for the total coliform distribution in
Grand Traverse Bay has been developed using continuity equations and experimental data
describing die-away kinetics. Advective and dispersive transport phenomena were
approximated using square-law assumptions and field dye tracer techniques. The predictive
capability of the model was verified by comparing model calculations with
observations during quasi-steady periods in 1963, 1964 and 1971. The utility of the
model was demonstrated with two examples showing coliform distributions resulting
from alternate waste disposal schemes. (Key words: Coliform bacterima;thematical
