Climate, Hydrology and Isotope Variability in Mediterranean Hydroecosystems

Dear Colleagues,

Regions with Mediterranean conditions are among the most affected by both human pressure (irrigation for agriculture, drinking water supply, industry, energy production, etc.) and climate variability. In these conditions, water availability still remains a limiting factor to human development but also to the preservation of high biodiversity hydroecosystems involving a lot of groundwater dependent ecosystems like coastal lagoons, wetlands, alluvial plains, etc. The maintaining of the key ecosystem services (food production, flood mitigation, carbon storage, recreation, etc) provided by such freshwater-dependant environments is then a major challenge for Mediterranean regions.

In order to promote new and improved knowledge on such environments as well as better management practises, hydrological investigations via isotope tools can help identify many fundamental hydrological and hydrogeological characteristics and parameters by combining different tools together and proposing new methodologies of survey.

Special attention will be given to studies involving investigations on isotopes in the atmosphere-soil-plant continuum, stable isotopes chronicles archived in plants and other material (shells, speleothem, etc) giving access to palaeo-hydrological reconstructions, isotope quantification of plant transpiration, groundwater recharge, and mixing processes tracing.

The aim of this Special Issue is to provide an overview of recent trends in Mediterranean hydrological studies involving isotope hydrology tools and focusing on the intricate interactions between atmospheric water, surface water, groundwater, and ecosystems. Topics will concern new investigations and findings linking together isotope hydrology and freshwater dependent ecosystems at any scale (region, watershed, aquifer, wetland, etc.)

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. 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.
