Dynamic identifiability analysis of the transient storage model for solute transport in rivers
Dynamic identifiability analysis transient storage model solute transport
2009/12/4
The use of dynamic mathematical models to simulate the behaviour of environmental systems is common practice. However, the output of these models remains uncertain, despite their widespread use and lo...
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...

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
2009/10/27
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...

2009/10/26
A numerical analysis of solute transport in two spatially heterogeneous fields is
carried out assuming that the fields are composed of ensembles of one-dimensional
non-interacting soil columns, each...
Solute Transport Measurements in Different Soil Types using Time Domain Reflectometry
Transport Measurements Soil Types Time Domain Reflectometry
2009/10/23
During recent years, time domain reflectometry (TDR) has proved to be a valuable tool for both water content (θ) and bulk electrical conductivity (σa) measurements. To allow resident solute concentrat...

Transect Scale Solute Transport Time Domain Reflectometry
2009/10/22
Two quasi steady-state solute transport experiments were carried out in a loamy
sand under field conditions. The flux was 40 mm/d in experiment 1 and 18.7
mm/d in experiment 2. Both water content (8...
Comparison of three stream tube models predicting field-scale solute transport
convective lognormat transfer stochastic stream tube solute transport
