STOMP. Subsurface Transport Over Multiple Phases

Abstract

STOMP is a computer model designed to be a general purpose tool for simulating subsurface flow and transport, that complements other analytical capabilities developed by Pacific Northwest National Laboratory`s Hydrology Group. The simulator was specifically designed to provide scientists and engineers from various disciplines with multidimensional analysis capabilities for modeling subsurface flow and transport phenomena. STOMP`s target capabilities were guided by proposed or applied remediation activities at sites contaminated with volatile organic compounds and/or radioactive material. Developed with the support of the U.S. Department of Energy, Office of Environmental Restoration and Waste Management, the simulator`s modeling capabilities address a variety of subsurface environments, including nonisothermal conditions, fractured media, multiple-phase systems, non-wetting fluid entrapment, soil freezing conditions, nonaqueous phase liquids, first-order chemical reactions, radioactive decay, solute transport, dense brines, nonequilibrium dissolution, and surfactant enhanced dissolution and mobilization of organics.
