Special Issue Information

Dear Colleagues,

The disciplines of hydrology and hydrogeology are commonly treated separately with research published in separate journals. Critically, however, there are dynamic interactions at the surface–ground water interface and interactions are complex, both spatially and temporally. Increasingly, and particularly in drier parts of the world, the impacts on surface waters affect groundwater resources, and vice versa, and in ways that are spatially and temporally hard to predict. This spatial and temporal variability of surface water–groundwater interactions requires integration of multiple lines of evidence to obtain an accurate, quantitative description of the water dynamics, which is required if we are to develop tools to predict potential timings and magnitudes of changes under different climate, anthropogenic, and natural impacts and provide science-based decisions for water management and distribution.

Contributions are invited that combine multiple strands of evidence and integrate research across traditionally disparate disciplines. That is, research that looks beyond the integration of hydrology, hydrogeology, geophysics, geochemistry, isotopes, and modelling to consider social responses, political imperatives, and pragmatic solutions to this complex issue. How do decisions made outside science influence a system’s response, and how do we monitor, measure, and incorporate science into policy? Papers are thus invited that provide scientific rigor to management decisions when dealing with surface-ground water interactions.

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.

While seawater intrusions are widely discussed, the salinization of coastal aquifers via narrow rivers is hardly documented. This study investigates groundwater dynamics in an aquifer next to an estuarine stream on the eastern Mediterranean coast. Groundwater levels and salinization patterns were examined as a response to dynamic changes in estuary water, both in low-and high-permeability aquifer units. In the high-permeability unit, the extent of salinization was relatively constant, reaching a distance of at least 80 m from the river, with no long-term changes in fresh-saline interface depth, indicating that the system is in a quasi-steady state. Groundwater salinity in the low-permeability unit showed frequent and large fluctuations (up to 36 and 22 at 5 and 20 m from the river, respectively). We suggest that the river may have a more immediate impact on a low-permeability than on a high-permeability aquifer. This is dependent on the history of seawater encroachments to the river, which are better preserved in the low-permeability unit, and on the hydrogeology of this unit, where sand lenses can serve as high-permeability conduits. However, this unit can efficiently prevent a large extent of salinization of the regional coastal aquifer by the estuary water. Full article
