Dear Colleagues,

Management of surface-water and groundwater resources requires knowledge of the groundwater system, which in turn requires an understanding of the configuration and properties of aquifers. Surface and subsurface geology can influence the hydrologic system and groundwater flow in numerous ways, including influencing the relative amounts of net infiltration, forming the subsurface architecture of aquifer and confining units, and faults that may either impede or focus flow. Geologic information can be considered during basin conceptualization, be used to construct digital 3D framework models, or be added during calibration of the numerical model.  This issue seeks to bring together hydrologists, geologists, and 3D framework and numerical modelers who create or use geologic data or 3D geologic framework models to inform regional groundwater models or resource assessments. Topics of interest include development and integration of geologic and hydrologic data, integration of geologic data and 3D geologic frameworks into groundwater models, hydrology and modeling studies that provide evidence for geologic controls on hydrology, and future avenues for advancing the use of geologic data in hydrologic studies. We aim for submissions that demonstrate novel approaches and case studies that integrate geologic and hydrologic data.

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.
