Special Issue Information

Dear Colleagues,

This Special Issue of Geosciences solicits original contributions on expansive soils and their shrinkage cracking mechanisms under different moisture stress (suction) and boundary loading (or constraints) conditions. The goal of this Special Issue is to gather high-quality original research articles, review articles, case histories, as well as short communications on recent advances on the understanding of behaviour of expansive soils and of effects of cracks on their volume change and hydraulic behaviour in the vadose zone (or moisture active zone).

We welcome contributions on fundamental and applied studies in geo-science and geo-engineering research and practice, including:

  • Volume Change:
    • Swelling
    • Shrinkage
    • Volume Change Index (e.g. relationship between volume change and moisture stress)
    • Effects and considerations of cracks on 3D volume change as well as one-dimensional volume change
    • Effects of drying and wetting cycles on volume change
  • Moisture Flow:
    • In a swelling soil
    • In a shrinking soil
    • Hydraulic Conductivity and Moisture Diffusion characteristics
    • Effects and considerations of cracks on moisture flow under swelling as well as shrinking soil conditions
  • Drying Shrinkage Cracks:
    • Occurrence, evolvement, and propagation of cracks (reasons and mechanisms)
    • Behaviour of cracks under moisture stress and boundary loading conditions
    • Effects of drying and wetting cycles on cracking behavior

Studies involving various levels of coupling (fully coupled models; sequentially coupled models, etc.) between the moisture flow and volume change with and without the effects of cracks in the unsaturated zone are also welcome.

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. Geosciences is an international peer-reviewed open access monthly 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 1800 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.
