近日,国际著名期刊《Journal of Hydrology》刊发了中国地质大学环境学院文章教授团队的最新研究成果——“A new model approach for reactive solute transport in dual-permeability media with depth-dependent reaction coefficients”。该文第一作者为环境学院2018级博士...
Pore-water exchange caused by ebullition of small oxygen bubbles produced by microalgae in the surface layer of sand sediment at St. Joseph Bay (SJB), Gulf of Mexico, was contrasted with ebullition o...
A comparative study is made among Laplace Transform Technique (LTT) and Fourier Transform Technique (FTT) to obtain one-dimensional analytical solution for conservative solute transport along unsteady...
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...
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...
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        font style='font-size:12px;'> 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...
A Review of Chemical Solute Transport Models      Review  Chemical Solute  Transport Models        font style='font-size:12px;'> 2009/10/27
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 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 ...
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...
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...
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...
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...
In this paper the relation between local- and field-scale solute transport parameters in an unsaturated soil profile is investigated. At two experimental sites, local-scale steady-state solute transp...
