<p>This paper presents an alternative numerical method to model the two dimensional contaminant transport through saturated porous media using a finite difference method (FDM) and finite element method (FEM). A finite-difference model is constructed by dividing ...

<p>Penetration of chemicals in the soil ground through irrigation water or rainfall induces important risks for the environment. These risks are badly known and may lead to direct contamination of the environment (atmosphere or ground water) or harmful effects ...

<p>The transport of contaminants has been a problematic issue for many years, mainly due to the adverse impact of the contaminants on the quality of groundwater. In order to analyse this, this study has developed a prediction model that allows the early detection ...

A comprehensive study on the chemical composition of rainwater was carried out in Obuasi, a gold mining town in Ghana. The result of this study generally suggests that rainwater chemistry in the area is strongly influenced by local anthropogenic sources (mining). ...

Performance of four different municipal solid waste landfill liner systems, i.e., Subtitle D composite liner system, composite liner system with a geosynthetic clay liner (GCL) instead of low permeability compacted soil, Wisconsin NR500 liner system, and proposed ...

In the framework of meshfree methods, in this study a methodology is developed based on radial point interpolation method (RPIM). This methodology is applied to a one-dimensional (1D) contaminant transport in the saturated porous media. The 1D form of advection-dispersion ...

Coastal aquifers are distinguished from other aquifers because of tidal effects which cause complicated groundwater flow and contaminant transport phenomena in regions immediately adjacent to the coast. This study is designed to address the significance of ...

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.

This research concerns, the mapping of the redox potential and the electrical conductivity of the groundwater, which are the key - parameters for the characterisation of contaminant plumes and for site remediation technologies.

A mathematical method called subordination broadens the applicability of the classical advection-dispersion equation for contaminant transport. In this method the time variable is randomized to represent the operational time experienced by different particles. ...
