Modelling fecal coliform bacteria. II: Model development and application.
The episodic nature of their origin and the transience of the receiving water response make the modeling of fecal coliform bacteria contamination events particularly challenging.
A two-layer mass balance model was developed to simulate spatial and temporal variability in fecal coliform bacteria concentrations in a polluted, urban lake.
Independently validated submodels were used to estimate bacteria loads from tributary and point source discharges, to quantify mass transport and to determine losses due to sedimentation and death.
The overall model was validated by successfully simulating spatial and temporal dynamics for dry weather conditions and two wet weather events.
