Special Issue Information

Dear Colleagues,

Semi-arid Tropics areas suffer from increasing surface water scarcity due to population growth and economic activity development. Therefore, groundwater has become an increasingly exploited resource for agriculture irrigation and drinking water supply. A consequence of this is an unbalanced situation between natural recharge and water abstraction, inducing water table depletion. Climate change will impact these tropical areas in various ways, increasing average temperature and changing rainfall patterns. Cost-effective groundwater management solutions are necessary in order to reduce the adverse impacts of these long term trends.

Contributions are expected on the following topics:

  • Evaluation of natural recharge in semi-arid areas
  • Characterization of groundwater flow in fractured aquifers
  • Estimation of groundwater reserves in heterogeneous aquifers
  • Managed aquifer recharge cost-benefit analysis
  • Climate change impact assessment on groundwater
  • Groundwater abstraction regulation
  • Groundwater numerical modeling

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 papers will be 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 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.

The Nubian sandstone aquifer is the only water source for domestic use and irrigation in the Kharga oasis, Egypt. In this study, 46 pumping tests are analyzed to estimate the transmissivity of the aquifer and to derive a spatial distribution map by geostatistical analysis and kriging interpolation. The resulting transmissivity values are log-normally distributed and spatially correlated over a distance of about 20 km. Representative values for the transmissivity are a geometric average of about 400 m2/d and a 95% confidence interval of 100–1475 m2/d. There is no regional trend in the spatial distribution of the transmissivity, but there are local clusters with higher or lower transmissivity values. The error map indicates that the highest prediction accuracy is obtained along the central north-south traffic route along which most agricultural areas and major well sites are located. This study can contribute to a better understanding of the hydraulic properties of the Nubian sandstone aquifer in the Kharga oasis for an effective management strategy. Full article
