The potential use of a nonlinear deterministic framework for understanding the dynamic nature of solute transport processes in subsurface formations is investigated. Time series of solute particle tra...
Solute transport in fractured media–analysis of non-reversibility in tracer tests
Solute transport fractured media non-reversibility tracer tests
2009/11/2
This paper describes several small-scale (laboratory) experiments designed to simulate solute transport through fractured formations. A block of granite was broken to produce a fracture similar to tho...
Modelling of Solute Transport in the Unsaturated Zone
Modelling Solute Transport Unsaturated Zone
2009/10/28
A numerical model for solute transport in the unsaturated zone has been
developed. The model is based on the basic equation for soil water flow in one
dimension and the general convection-dispersion...
Laboratory Experiments on Solute Transport in Non-Homogeneous Porous Media
Laboratory Experiments Solute Transport Non-Homogeneous Porous Media
2009/10/27
Solute transport in groundwater is a process which has become of major importance
during the last decades due to increasing contamination of ground
water. This process usually occurs in a medium het...
This paper presents a review of groundwater models capable of simulating solute transport
(i.e. advection-dispersion) and equilibrium chemistry processes.
Introductory, basic model components are di...
The Effect of Heterogeneity on Large Scale Solute Transport in the Unsaturated Zone
Effect of Heterogeneity Large Scale Solute Transport Unsaturated Zone

The effect of natural heterogeneity on large scale solute transport in the unsaturated
zone is investigated using stochastic methods. Several of the physical
parameters that control flow and solute ...
Spatial Variability of Physical Parameters and Processes in Two Field Soils Part I:Water Flow and Solute Transport at Local Scale
Spatial Variability Physical Parameters Two Field Soils Local Scale
2009/10/26
Natural field systems exhibit a large degree of soil heterogeneity which affects
the movement of water and solutes and thus leads to highly varying observations
of water contcnt and solute concentra...
