The major objective of this Special Issue is to examine the interdependencies between the natural host rock barrier that surrounds a high level waste repository and the engineered barriers that protect the waste within it. A significant challenge in engineering barrier design is predicting the long-term behaviour of the bentonite, or other sealing material, at the interface between the barrier and the geosphere and at the interface between the barrier and the waste canister. The repository presents extreme environmental conditions alongside a requirement for understanding barrier material behaviour over very long, million-year, timescales. Over such times-scales, conditions at the interfaces between barriers will change. For example, freshwater ingress may occur due to glacial melting, high pH groundwater may result from cement leaching in remote parts of the repository, and microbial populations may evolve to utilise energy derived from the waste.
This Special Issue aims to provide an outlet for rapid, widely accessible publication of peer-reviewed studies that explore the behaviour of engineered barriers over time subject to changing environmental conditions within the host rock and waste packages. Such changes may include temperature variations, pH, fluid geochemistry, gas liberation, and biological mediation of these changes. Research submissions that comprise laboratory experiments, field trials and/or model development are welcomed.

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 1500 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.
