The model solves the solute transport equation for both hydrocarbon and oxygen, assumes an instantaneous reaction between oxygen and hydrocarbon, and combines the two plumes using the principle of superposition.
Computations account for convection, dispersion, mixing, and biodegradation effects.
Also, the program can simulate slow hydrocarbon plumes undergoing biodegradation and can simulate in-situ biorestoration schemes such as the injection of oxygenated water. Moreover, the model can simulate reaeration and anaerobic biodegradation as a first-order decay in hydrocarbon concentrations. Please contact Rice University if you have any questions.
