    Modeling of soil moisture and solute transport in the unsaturated zone has been under development since the s (e.g. Toksoz and Kirkham, ; Neuman et al., ; Zaradny and Feddes, ). Early soil water flow models were further extended with routines for specific phenological and physiological crop development and solute by: @article{osti_, title = {Stochastic analysis of transport of conservative solutes in caisson experiments}, author = {Dagan, G.}, abstractNote = {The Los Alamos National Laboratory has conducted in the past a series of experiments of transport of conservative and reactive solutes.

Drake and Zhixun Lin Dynamac Corporation Oakridge Boulevard Ada, OK David G. Jewett Subsurface Protection and Remediation Division National Risk . Solute transport studies involving layered media are important for investigating how restricting layers affect rates of solute migration in the soil profile and, more generally, for examining the influence of soil heterogeneity on solute transport. Analytical solutions of the one-dimensional advection-dispersion equation (ADE) were obtained.

Butters et al. (this issue) are used to compare two models of vadose zone solute transport: the. The MT3DMS groundwater solute transport model was modified to simulate solute transport in the unsaturated zone by incorporating the unsaturated-zone.

This study presents the test of the widely used model MIKE SHE at the lysimeter in Wagna in Southern Styria (Austria). At the lysimeter comprehensive data of vegetation, i.e., cultivation types, and soil hydraulic properties are available to parameterise the model. The aim of the study is to test the water movement and solute transport simulation in the unsaturated zone Cited by: 2.

An experiment is designed to perform tracer tests in an unsaturated fractured rock with a horizontal fracture. Data from an intact and an artificial sandstone sample was collected and used to discuss the effect of the fracture on tracer migration.

The delay time of the tracer in the fracture was further determined in terms of the fracture aperture by: 3. Compilation of field-scale caisson data on solute transport in the unsaturated zone.

Finally, an application on the Seine basin show that solute transfer velocities are lower with NonsatVG than with NonsatSW, but in better agreement with literature.

The data were analyzed using the method of moments. In addition to the solute transport experiments, a detailed set of physical properties of the field was obtained by excavating three pits to a depth of m and also by taking soil cores throughout the study by: Solute transport in low-permeability media such as clay has not been studied carefully up to present, and we are often unclear what the proper governing law is for describing the transport process in such media.

In this study, we composed and analyzed the breakthrough curve (BTC) data and the development of leaching in one-dimensional solute transport experiments in Cited by: 5.

Solute transport at laboratory scale through a homogenized soil column and through natural soil at field-scale differs chiefly in the vastly increased spatial variability of the transport volume found in the latter.

Such large-scale variations are generally described by spatially variable parameter fields. However, small-scale variations Cited by: Cvetkovic VD, Destouni G () Comparison between resident and flux-averaged concentration models for field-scale solute transport in the unsaturated zone.

In order to account for different soil horizons, the profile was divided into two different layers, for each of which six parameters had to be optimized to simulate the water and solute transport of the unsaturated zone: On the one hand the five parameters (θr, θs, α, n, Ks) that describe the water retention and hydraulic conductivity.
