Development of a General Conceptual-numerical Model to Simulate the Fate and Subsurface Transport of Explosives, and the Moisture and Temperature Signatures Around Land Mines

摘要

We have developed a general conceptual-mathematical model is applicable to the fate and advective-dispersive transport of most explosives and its metabolites in the vadose zone or groundwater. The model accounts for the most important physical, chemical and biological processes known or hypothesized to affect the behavior and simultaneous transport of the major explosives (the parent products) such as TNT or RDX, and its various metabolites, as they are being sequentially created by degradation of the parent compound. The parent and daughter compounds are allowed to have different mobilities in the subsurface as dictated by their specific dissolution, sorption and transport properties.
