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 کاملLaboratory Method for Estimating Solute Transport Parameters of Unsaturated Soils
Modeling the contaminant transport process in soils requires the solute transport parameters. Displacement experiments were carried out on soil columns (Sand – Silt – Clay) by injecting a solution of 0.8 M KCl in a steady state. Breakthrough curves are symmetrical, characteristics of an equilibrium solute transport. The hydrodynamic dispersion coefficients were estimated by optimizing the measu...
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 کاملLaboratory, Field, and Modeling Analysis of Solute Transport Behavior at the Shale Hills Critical Zone Observatory
We collected and analyzed breakthrough curve (BTC) data to identify the parameters controlling transport from a series of undisturbed fully saturated soil cores and a field test at the Shale Hills Critical Zone Observatory in central Pennsylvania. The soil cores were collected in a continuous hole extending across the soil profile vertically at one location to quantify how solute transport beha...
