Advances in Hydrological and Hydrogeochemical Processes and Water–Rock Interactions under Complicated Conditions and Changing Environments

Dear Colleagues,

Water is the key ingredient in human beings’ survival and the most abundant substance on the surface of Earth; it also connects the four spheres of the earth (hydrosphere, biosphere, lithosphere, and atmosphere). Thus, an increasing number of studies focus on its circulation, distribution, movement on Earth, and interactions with other substances, including its responses to human activities. Scientific understanding of the hydrological processes, hydrogeochemical processes, and water–rock interactions under complicated circumstances is an important research hotspot in the field of hydrology and earth system sciences. In particular, both global climate change and high-intensity human activities dramatically alter the hydrological cycle and its associated processes, posing a threat to future sustainable water resource management in global and regional areas. Therefore, it is urgent that we improve our skills and methods to better understand the physical mechanisms and responses of hydrological and hydrogeochemical processes to changing environments. This requires multidisciplinary studies that involve hydrology, hydrogeology, hydrogeochemistry, ecology, environmental sciences, etc.

We invite researchers to contribute original research articles and state-of-the-art reviews, including in situ and laboratory experiments; theoretical models; and numerical simulations for hydrological and hydrogeochemical processes and water–rock interactions. Potential topics include, but are not limited to, the following:

• Improving estimates of hydrological processes in changing environments;
• Quantifying the effects of climate change and human activities on hydrological changes;
• Refined numerical simulation of hydrological processes under complicated conditions;
• Integrated surface and subsurface water modeling for areas or basins affected by high-intensity human activities;
• New model structures and methods for modeling hydrological processes;
• Big data and artificial intelligence in hydrological modeling;
• Water chemistry–microbial coupled interactions of water quality formation and evolution in coal mine;
• Migration and transformation of hydrochemical components in the interaction zone between surface water and groundwater;
• Natural processes of water–rock interactions and the migration and cycling of chemical components in geological environments;
• Physicochemical processes within intricate porous media and the dynamic evolution of medium permeability;
• Fluid flow and mineral reactions pertinent to environmental engineering applications, including, but not limited to, nuclear waste disposal, carbon dioxide sequestration, and site remediation;
• Coupled mechanisms governing water quality evolution in mining areas alongside advanced pollution-mitigation strategies;
• Investigations into numerical simulations of reactive solute transport and advanced research on model parameter estimation;
• Novel approaches for the effective assessment of remediation technology and strategies for site contamination.

We look forward to receiving your contributions.

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. Sustainability 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 2400 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.
