Special Issue Information

Dear Colleagues,

The Special Issue entitled “Coupled Flow and Reactive Transport Processes in Subsoil” focuses on the use of analytical or numerical approaches concerning flow and reactive transport processes in aquifers. Several essential and practical issues of the reactive transport processes within the vadose and saturated portions of aquifers, which are crucial to solve engineering and environmental problems, have not yet been understood in detail and are still not widely used to support decision-making processes.

The numerical quantitative approach offers the opportunity to better identify and understand the physical and biogeochemical processes’ dynamics which happens in the aquifer, occurring both in the vadose and saturated zone of aquifers and helping scientists and technicians to identify the most effective solutions.

Our goal is to gather manuscripts discussing the mentioned topics, including recent experimental, analytical, and numerical results related to the study of complexities in reproducing flow and reactive transport processes in variably saturated porous media across a wide range of spatial and temporal scales (including uncertainty analysis and risk assessment of operations).

In particular, we warmly welcome contributions related to the following topics of interest:

  • Flow processes in porous media and fractured rocks.
  • Reactive transport processes in the vadose zone and saturated portions of aquifers.
  • Biogeochemistry and reactive transport.
  • Isotope fractionation models.
  • Coupled hydraulic, thermal, chemical, and biological processes.
  • Recent laboratory experiments on the main parameters affecting reactive transport processes in subsoil.
  • Advanced numerical modeling or analytical framework and methods.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The subsurface injection of nanoscale zero-valent iron particles (nZVI) for the in situ reductive remediation of contaminated aquifers has grown over the last 25 years. However, several efforts are still being made to improve the stability and delivery of nZVI and to simplify the procedure for site-specific injection design. In this study, the injectability and mobility of a commercial nZVI-based reactive gel was tested in a radial geometry laboratory setup. The gel proved to be highly mobile in sandy porous media, allowing for the achievement of a radius of influence (ROI) of 0.7 m with a homogeneous nZVI distribution within the domain. The experimental results therefore confirmed that nZVI permeation injection with a good radius of influence is possible in conductive formations. The software MNMs 2023 (Micro- and Nanoparticle transport, filtration, and clogging Model-Suite) was then applied to model the radial transport experiment and extrapolate results with the aim of developing a new graphical tool for simple and effective nZVI permeation injection design. For this purpose, 1800 numerical simulations were performed to build two multiparametric maps to predict the expected ROI in two typical aquifer lithologies and over a wide range of operating conditions.
