Special Issue Information

Dear Colleagues,

Coastal aquifers are of paramount importance for human society because most of the world’s population live in coastal areas, and these areas represent the main water sources for drinking water, agricultural and industrial uses.

The intense exploitation and dispersion of contaminants make these areas prone to severe environmental threats, exacerbated by ongoing climate changes, leading to sea level rise, deep alterations in the space/time distribution of precipitation, and higher evapotranspiration rates, which endanger the quality and quantity of renewable coastal water resources.

The aim of this Special Issue is to present original research and review articles that discuss field observations, models and novel methods and strategies concerning the processes governing the water cycle in coastal areas, in the context of a changing environment under anthropic pressure.

Potential topics include, but are not limited to, the following:

  • Resistance and resilience of coastal aquifers to climate change;
  • Hydro-geochemical tools for monitoring coastal aquifer dynamics;
  • Contaminant pathways in coastal aquifers and remediation strategies;
  • Saline wedge intrusion and remediation;
  • Eco-sustainable exploitation strategies for coastal aquifers.

We are looking forward to receiving your contributions.

Dr. Paolo Madonia
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at 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.

Coastal areas situated at lower elevations are becoming more vulnerable to flooding as a result of the accelerating rise in the global sea level. As the sea level rises, so does the groundwater. Barriers designed to shield against marine flooding do not provide protection against flooding caused by rising groundwater. Despite the increasing threat of groundwater flooding, there is limited knowledge about the relationship between sea level rise and groundwater fluctuations. This hinders the ability to adequately consider sea level rise-induced groundwater flooding in adaptation initiatives. This study aims to investigate how local groundwater in Juelsminde, Denmark, responds to changes in sea level and to evaluate the predictability of these changes using a machine learning model. The influence of the sea on the shallow groundwater level was investigated using six groundwater loggers located between 45 and 210 m from the coast. An initial manual analysis of the data revealed a systematic delay in the rise of water levels from the coast to inland areas, with a delay of approximately 15–17 h per 50 m of distance. Subsequently, a support vector regression model was used to predict the groundwater level 24 h into the future. This study shows how the groundwater level in Juelsminde is affected by sea level fluctuations. The results suggest a need for increased emphasis on this topic. Full article
