Special Issue Information

Dear Colleagues,

Karst aquifers play a crucial role in supplying water, with almost 10% of the global population relying on karst water for drinking purposes. In certain countries like Slovenia and Austria, where carbonate rocks are abundant, more than 50% of the total water consumption is sourced from karst aquifers. However, extended dry periods can lead to a decrease or even cessation of spring discharge, thereby jeopardizing the continuity of water supply that relies on karst water.

Apart from being important sources of water, karst springs also pose significant risks to human populations. Flash floods caused by unexpected surges in spring water can endanger infrastructure and human lives. Moreover, bacterial epidemics can occur due to the rapid transport of contaminants through karst conduits during flood events, posing significant health risks.

Climate change projections from organizations like the Intergovernmental Panel on Climate Change (IPCC) indicate that there will be notable temperature increases and changes in precipitation patterns throughout the remainder of the 21st century. These alterations in climate conditions will lead to changes in extreme weather events with increased intensity, frequency, spatial extent, duration, and unusual timing, consequently raising concerns about potential unprecedented extreme events.

The scope of the Special Issue is to collect high-quality papers discussing the impacts of climate change on karst water resources. This will provide a unique collection of papers on the topic for readers interested in state of the art of climate research and karst.

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 250 words) can be sent to the Editorial Office for assessment.

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.

This paper introduces a methodology for forecasting spring hydrographs based on projections from regional climate models. The primary study objective was to evaluate how climate change may affect spring discharge. A statistical–analytical modeling approach was developed and applied to the Jósva spring catchment in the Aggtelek Karst region of Hungary. Historical data served to establish a regression relationship between rainfall and peak discharge. This approach is particularly useful for predicting discharge in cases where only historical rainfall data are available for calibration. Baseflow recession was analyzed using a two-component exponential model, with hydrograph decompositionand parameter optimization performed on the master recession curve. Future discharge time series were generated using rainfall data from two selected regional climate model scenarios. Both scenarios suggest a decline in baseflow discharge during different periods of the 21st century. The findings indicate that climate change is likely to intensify hydrological extremes in the coming decades, irrespective of whether moderate or high CO2 emission scenarios unfold. Full article
