Trends and Variations in Hydroclimatic Variables: 2nd Edition

Dear Colleagues,

This Special Issue invites studies that investigate the seasonality, trends, and variations in space and time in the main hydroclimatic variables that, interrelated with precipitation, affect evapotranspiration (drought/aridity) and water availability through other components of the hydrological cycle, such as flow/floods, water levels in reservoirs (lakes and dams), and groundwater. These variables play a crucial role in understanding and managing water resources, predicting climate impacts, and in addressing various environmental, ecological, productive, economic, social and public health issues. The integration of hydroclimatic variable data into decision-making processes is crucial to deal with the multifaceted impacts of climate change and ensure sustainable development.

Although hydroclimatic variables are indispensable for several applications, their complexity and variability present challenges in analysis and prediction. The influence of geographic and astronomical factors, mesoscale atmospheric phenomena, and climate change on these variables indicates the need for continuous monitoring and advanced modeling techniques to improve our understanding of the management of water resources and related systems.

The methods used to analyze trends and variations in hydroclimatic variables in space and time can be grouped into three categories: (a) statistical, (b) machine learning, and (c) deterministic/physics-based. The objective of this Special Issue is to group together a collection of articles that present a range of methodological approaches for understanding hydroclimatic variations. The topics covered in this Special Issue include the following, among others:

• Studies aimed at monitoring systems and direct measurements of hydroclimatic variables;
• Studies aimed at statistical hydrology, with the aim to define the patterns, probability distribution functions, and return time of hydroclimatic variables;
• Analysis of trends and variations in time series of hydroclimatic variables;
• Analysis of extreme events (droughts, floods);
• Detection of spatial variations and trends in hydroclimatic variables;
• Future effects of climate change on hydroclimatic variables;
• Geostatistical methods in remote sensing and GIS for assessing the impact of climate change;
• Assessment of the impact of climate change using hydrological modeling of surface and groundwater at the scale of river basins or aquifers;
• Impact of climate change/disturbances on water use for agriculture (including irrigation and drainage);
• Impact of climate change/disturbances on natural ecosystems and ecosystem services.

We look forward to receiving your original research articles and reviews.

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. Hydrology 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.
