Résumé :
Finite –Element Flow Transport Model for the Saturated/Unsaturated Zones in 2d/3-D
BioF&T 3-D, by Resources and Systems International (RASI), models flow and transport in the saturated and unsaturated zones in two or three dimensions in heterogeneous, anisotropic porous media/fractured media. BIOF&T 3-D allows real world modeling not available in similar packages. Model convection, dispersion, diffusion, adsorption, desorption, and microbial processes based on oxygen-limited, anaerobic, first-order, or Monod-type biodegradation kinetics as well as anaerobic or first-order sequential degradation involving multiple daughter species.
FEATURES
• Transient 1-D or 2-D Cartesian (x,z) or 2-D Radial (r,z) water flow and multispecies dissolved phase transport solution in the unsaturated zone uncoupled with 2-D or 3-D flow and multi-component aqueous phase transport in ground-water aquifers. This feature enables computationally-efficient simulations and gives due regard to the dimensionally of the problem and is hydrogeological defensible.
• An option for fully-coupled 3-D simulations of unsaturated and saturated zones for extremely complicated conditions.
• Temporal and spatial variations in the source (i.e., residual dense or light nonaqueous phase liquids and/or other non point contamination) and, given the initial conditions, changes in loading to ground water are computed and updated internally.
• Spatial variation in recharge/injection.
• Model multiple pumping and/or injection wells, or trenches.
• Simulation of heterogeneous and/or anisotropic porous media with (or without) fractures based on a dual porosity approach.
• Rectangular 2-D/3-D prism or isoparametric quadrilateral/hexahedral elements to accurately model irregular domain and material boundaries, hydraulic, and physical boundaries.
• Convection, dispersion, diffusion, adsorption, desorption, and microbial processes based on oxygen-limited, first-order, or Monod-type biodegradation kinetics, as well as anaerobic sequential degradation involving multiple daughter products. This allows real-world modeling not accomplished in similar biodegradation packages.
• Computationally-efficient matrix solution by conjugate gradient method with preconditioning.
• BIOF&T allows highly-accurate representation of irregular site boundaries, uneven ground surface and complex subsurface geology with the three-dimensional Mesh Editor.
