Special Issue Information

Dear Colleagues,

Water resources are a national source of wealth, and their availability is essential to sustain life and human activities. The amount and availability of water resources in the world varies spatially and temporally, with an increasing number of places facing severe water shortages.

It is predicted that climate change will significantly affect the spatio-temporal distribution of water resources, leading to the transformation of the water cycle in the catchment and changes in the structure of the water balance. An increase in deep low flows in rivers is expected, which may reduce surface water and groundwater resources. In lowland catchments, evapotranspiration will increase at the expense of water resources, causing a reduction. The acceleration of the hydrological cycle may lead to more and more frequent water-related extreme events, including droughts and floods, and the expected changes in water resource availability may lead to periodic deficits in the water supplied to the population, as well as shortages in agriculture and forestry, which may entail severe socio-economic losses.

Being aware of these threats and taking action to mitigate their future effects is necessary.

Current forecasts of water consumption trends resulting from socio-economic development and the climatic changes that overlap with them are subject to considerable uncertainty. Climate models (global circulation of the atmosphere) and demographic and economic development models do not yet allow for precise projections of changes in the hydrological cycle and water resource availability.

This Special Issue invites researchers to present their results of new findings from the assessment and modeling of hydrological processes and water resources under the conditions of climate change, regularities in their spatio-temporal variability in relation to water management, and the related threats.

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.

This study explores the impacts of climate change on the number of dry days and very heavy precipitation days within Iran’s metropolises. Focusing on Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz, the research utilizes the sixth phase of the Coupled Model Intercomparison Project (CMIP6) Global Circulation Models (GCMs) to predict future precipitation conditions under various Shared Socioeconomic Pathways (SSPs) from 2025 to 2100. The study aims to provide a comprehensive understanding of how climate change will affect precipitation patterns in these major cities. Findings indicate that the SSP126 scenario typically results in the highest number of dry days, suggesting that under lower emission scenarios, precipitation events will become less frequent but more intense. Conversely, SSP585 generally leads to the lowest number of dry days. Higher emission scenarios (SSP370, SSP585) consistently show an increase in the number of very heavy precipitation days across all cities, indicating a trend towards more extreme weather events as emissions rise. These insights are crucial for urban planners, policymakers, and stakeholders in developing effective adaptation and mitigation strategies to address anticipated climatic changes. Full article
