Special Issue Information

Dear Colleagues,

Soil and groundwater pollution is one of the most relevant environmental problems associated with urban, industrial, and agricultural activities. Numerical modeling techniques are considered to be essential tools used to analyze environmental risks and ensure the correct design of remediation strategies. These hydrogeological modeling techniques refer to the analysis of fate and transport of pollutants, both in the aquifer (saturated zone) and in the soil (vadose zone).

The purpose of this Special Issue is to show the current state of recent research related to the development and the application of numerical models to real case studies. Pollution problems may derive from organic contaminants (e.g., VOC's, pesticides, hydrocarbons) or inorganic contaminants (e.g. salts, heavy metals, radionuclides).

Potential topics include, but are not limited to, the following:

  • Groundwater flow and transport modeling in the saturated zone;
  • Unsaturated flow and transport modeling;
  • The development of novel models to address soil/groundwater heavy metal pollution;
  • The development of novel models to address soil/groundwater pesticide pollution;
  • The development of novel models to address soil/groundwater NAPLs pollution;
  • The use of numerical modeling techniques to the design of remediation techniques: successful case studies.

We look forward to receiving your contributions.

Strengthening the transmission uniformity of remedial amendments in heterogeneous porous media is important for improving in situ groundwater remediation efficiency. This study developed a characterization method to represent the improvement of transmission uniformity in heterogeneous media using the degree of difference in hydraulic conductivity of porous media between xanthan solution and pure water, which was defined as the transmission uniformity control coefficient U. Research results showed that U of medium sand/fine sand (2.44) was the most ideal among the three medium combinations tested when the concentration of xanthan solution was 100 mg/L. Then, factors that may influence U were analyzed, and the obtained results showed that xanthan’s control ability is affected by permeability contrast (media combinations) and polymer concentration. Generally, when concentrations were in the range of 100~800 mg/L, Umf > Ucf > Ucm. Finally, the actual degree of polymer propulsion under different concentrations and media combinations was analyzed, and the obtained results showed that as different media were varied in permeability change degree, while the migration speed presented an overall decrease as the concentration increased, where the maximum migration front in the low-permeability zone (LPZ) was more obvious than that in the high permeability zone (HPZ). This was consistent with the results characterized by U. Full article
