Special Issue Information

Dear Colleagues,

Faced with the growing impacts of climate change, hydrogeology plays a key role in the management of groundwater resources, which is why this Special Issue explores the scientific advances that make the invisible visible by integrating innovative tools and approaches such as geomatics, geographic information systems (GISs), remote sensing-based Earth observation data, and artificial intelligence.

Selected articles deal with the influence of climate on the hydrological cycle and, in particular, the impact of drought and flooding on aquifers. Thanks to prediction methods based on hydrological modeling and machine learning, this Special Issue highlights strategies for adapting to water-related natural hazards.

It will also feature applied research on groundwater assessment, aquifer recharge, and water resource vulnerability by harnessing the power of geospatial data and predictive models, offering solutions for more effective and resilient groundwater management in the face of climate challenges.

The Special Issue highlights innovative approaches combining remote sensing and GIS tools to map water resources and optimize their sustainable use. Thanks to advances in numerical hydrogeology and predictive modelling, this Special Issue provides concrete solutions to the challenges linked to the availability and vulnerability of groundwater resources, and also for more efficient and resilient management in the face of climate challenges.

This Special Issue is aimed at researchers, engineers and decision-makers wishing to integrate modern hydrological technologies to anticipate and mitigate the effects of climate change on water resources.

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 250 words) can be sent to the Editorial Office for assessment.

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.

Mesa de Los Santos is an elevated plateau of the Eastern Cordillera of Colombia bordered by escarpments, where groundwater resources are limited to the local recharge. The geological unit with the greatest hydrogeological potential is Los Santos Formation (Lower Cretaceous), which presents three members (Lower, Medium and Upper). Based on stratigraphic information and hydrogeological information, three aquifer systems were characterized in the Upper Member: The Shallow Aquifer System (SAS), the Upper Aquifer 1 (UA1), and Upper Aquifer 2 (UA2). The SAS comprises discontinuous aquifers with groundwater flowing very close to the surface, circulating through weathered and fractured levels. UA1 and UA2 contain groundwater flowing through fractures. Groundwater in UA1 circulates through the top of the Upper Member, is underlain by a predominantly muddy base and exhibits an E-W and NE-SW flow consistent with the dip of the layers and the main directions of fractures. UA2 groundwater flows through the base of the Upper Member and is limited by the impermeable Middle Member. Stable water isotopes (δ18O, δ2H) data show three behaviors: (i) large temporal variability indicating a rapid flow through fractures in the three aquifers, and through primary porosity mainly due to weathering in the SAS; (ii) slower flows, with low temporal variability, showing well-mixed water of meteoric origin in the SAS, UA1, and UA2; (iii) groundwater with signs of evaporation indicating the connection between wetlands and the SAS in some cases.
