Abstract: | |
BIOPLUME II is a two-dimensional solute transport model to compute changes in concentration over time due to advection, dispersion, mixing, and retardation. The model simulates the transport of dissolved hydrocarbons under influence of oxygen-limited biodegradation. It also simulates reaeration and anaerobic biodegradation as a first order decay in hydrocarbon concentrations. BIOPLUME II is based on the USGS 2D solute transport model MOC (Konikow-Bredehoeft). It solves the transport equation twice: once for hydrocarbon and once for oxygen. As a result, two plumes are computed at every time step, and the two plumes are combined using the principle of superposition. The model assumes an instantaneous reaction between oxygen and hydrocarbon. It can simulate natural biodegradation processes, retarded plumes, and in-situ bioremediation schemes. The model allows injection wells to be specified as oxygen sources into a contaminated aquifer. It also provides three additional oxygen sources: 1) initial dissolved oxygen in the uncontaminated aquifer; 2) natural recharge of oxygen across the boundaries; and 3) vertical exchange of oxygen from the unsaturated zone. BIOPLUME II comes with a preprocessor and handles a 20 X 30 cell grid. The also comes with a postprocessor which can convert output data to a format usable by commercial contouring packages.
