Time-lapse electrical resistivity anomalies due to contaminant transport around landfills
landfill hydrogeological modeling salinity resistivity geophysical forward and inverse modeling
2015/9/2
The extent of landfill leachate can be delineated by geo-electrical imaging as a response to the varying electrical
resistivity in the contaminated area. This research was based on a combination of h...

Contaminant transport to public water supply wells via flood water retention areas
Contaminant transport public water supply wells flood water retention areas
2009/12/8
The essential processes and mechanisms of the transport of contaminants from a river to a well field via a flood water retention area are presented. The transport is conceptualized as a succession of ...
Investigation of a parameter estimation method for contaminant transport in aquifers
Investigation parameter estimation method contaminant transport aquifers
2009/12/4
Real world groundwater aquifers are heterogeneous and system variables are not uniformly distributed across the aquifer. Therefore, in the modelling of the contaminant transport, we need to consider t...
Fuzzy rule-based model for contaminant transport in a natural river channel
Fuzzy rule-based model contaminant transport natural river channel
2009/12/4
Fuzzy rules are used to model solute dispersion in a river dead zone, such that the turbulent diffusion is determined by a fuzzy inference system which relates the local mean velocity shear to the lon...
Parametrization of Contaminant Transport through an Anisotropic Unconfined Aquifer
Parametrization Contaminant Transport Anisotropic Unconfined Aquifer
2009/10/28
A duo two-dimensional deterministic model of contaminant transport through
a homogeneous and anisotropic unconfined aquifer is developed. This model
is then utilized to evaluate the effects of such ...
An Evaluation of the Importance of Transmissivity,Head and Concentration Data for Contaminant Transport Modelling
Importance of Transmissivity Concentration Data Contaminant Transport Modelling
2009/10/27
The 3 basic data types of contaminant hydrology are examined by stochastic
modelling of a groundwater contamination case. The stochastic transport model,
which is of the Monte Carlo type, uses a num...
Spatial Variability of Contaminant Transport in a Fractured Till,Avedøre Denmark
Spatial Variability Contaminant Transport Fractured Till
2009/10/23
A field experiment shows that rapid downward migration of solutes and microorganisms
can occur in a fractured till. A solute tracer, chloride, and a bacteriophage
tracer, PRD-1, were added to ground...
Evidence for deep sub-surface flow routing in forested upland Wales: implications for contaminant transport and stream flow generation
bedrock groundwater Hafren hillslope hydrology Plynlimon recharge soil water streamflow generation
2009/3/5
Upland streamflow generation has traditionally been modelled as a simple rainfall-runoff mechanism. However, recent hydrochemical studies conducted in upland Wales have highlighted the potentially imp...
April 16, 2007，RICHLAND, Wash. – The Department of Energy recently granted Pacific Northwest National Laboratory $27.5 million dollars over 5 years to investigate the movement of contaminated groundwa...
