Modelling of Water Flow and Solute Transport in Double Porosity Unsaturated Media: Theory, Two-scale Computations and Experiments
“Multi-scale, multi-components, multi-phases” are the key words that characterize the double porosity media, like fissured rocks, aggregated soils or composite geomaterials, subject to environmental conditions. In relation to this context an integrated upscaling approach to the modelling of water flow and solute transport under unsaturated conditions in double porosity media, is presented. The ...
متن کاملSolute transport along preferential flow paths in unsaturated fractures
Laboratory experiments were conducted to study solute transport along preferential flow paths in unsaturated, inclined fractures. Qualitative aspects of solute transport were identified in a miscible dye tracer experiment conducted in a transparent replica of a natural granite fracture. Additional experiments were conducted to measure the breakthrough curves of a conservative tracer introduced ...
متن کاملA Solute Flux Approach to Transport through Bounded, Unsaturated Heterogeneous Porous Media
framework. In Eulerian approaches, measurements of a quantity, say the solute concentration, are taken at In this paper, we present a solute flux approach for analyzing solute fixed locations by preinstalled samplers. At any time transport statistics in statistically nonstationary, unsaturated flow. Flow nonstationarity in the vadose zone may arise from a number of the concentration field is ch...
متن کامل78: Models of Water Flow and Solute Transport in the Unsaturated Zone
A large number of models for simulating water flow and solute transport in the unsaturated zone are now increasingly being used for a wide range of applications in both research and management. Modeling approaches range from relatively simple analytical and semianalytical solutions, to complex numerical codes. While analytical and semianalytical solutions are still popular for some applications...
متن کاملSolute transport during cyclic flow in saturated porous media
We consider materials with large pores interconnected by thin long channels saturated with an incompressible fluid. In the absence of fluid flow, solute transport in the porous network is diffusion controlled, however, solute transport can be enhanced when the porous network is subjected to a cyclic flow with zero time average velocity. We develop a mathematical model to analyze this physical p...
