heat and contaminant transport in unsaturated soil
solute transport in unsaturated porous media can be viewed as a coupled phenomenon with waterand heat transport, together with mechanical behaviour of media. in this paper, solute transport is formulatedmathematically considering heat and water flow in deformable porous media. advection, dispersion anddiffusion of chemical species in the liquid phase are considered. convection and conduction fo...
متن کاملTREX: spatially distributed model to assess watershed contaminant transport and fate.
Contaminant releases from upland areas can have adverse water quality and stream ecology impacts. TREX (Two-dimensional, Runoff, Erosion, and Export) is a spatially distributed, physically-based model to simulate chemical transport and fate at the watershed scale. TREX combines surface hydrology and sediment transport features from the CASC2D watershed model with chemical transport features fro...
متن کاملEvaluation of Optimum Landfill Design by Contaminant Transport Analysis
Contaminant transport analysis was performed for four selected solid waste landfill designs using the computer code POLLUTE. The diffusion coefficients were determined for the natural soils (aquitard) and compacted soils from the Urumia landfill site, using the diffusion tests. These coefficients along with the geometrical, physical, and chemical parameters of the natural soil and engineered la...

متن کاملModeling Contaminant Transport in Plants
In order to predict the fate of contaminant transport in plants, experiments were conducted and simple models were used to simulate the processes. Diffusion experiments were carried out to estimate contaminant diffusivity within plant roots, while adsorption experiments were used to investigate the adsorption of contaminant in plant stems. We found that plants can enhance the removal of trichlo...
