Special Issue Information

Dear Colleagues,

A large number of rivers worldwide are being hydromorphologically altered by climate- and human-induced changes. Additionally, climate-change- and human-induced changes are driving an increase in extreme events. This leads to greater occurrences of water hazard events such as droughts and floods. Due to the increase in large hydropower dams planned across the world, most of the river basins will be severely regulated. Rivers will adjust to disturbances in a very complex way.

This Special Issue aims to offer an appropriate avenue for discussing and disseminating recent developments in hydrological and fluvial processes, coming from students, researchers, and professionals working in careers linked to water.

For this Special Issue, papers reporting theoretical, field, laboratory, and numerical investigations on hydrological and fluvial processes are welcome.

Authors are encouraged to submit their manuscripts related to the following topics:

  • Hydrological processes;
  • Water related hazards under the global climate change;
  • Fluvial processes;
  • Human impacts on fluvial system;
  • Risk mitigation.

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. 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.

The sagebrush steppe ecosystem plays a critical role in water cycling in arid and semiarid landscapes of the western United States; yet, there is limited information regarding individual sagebrush plant water uptake. We used the stem heat balance (SHB) method to measure transpiration in mountain big sagebrush (Artemisia tridentata subsp. vaseyana) plants in a semiarid rangeland ecosystem in central Oregon, Pacific Northwest Region, USA. We evaluated the relationship between sagebrush transpiration and environmental factors from July 2022 to May 2023 for two individual plants representative of the average sagebrush stand height and crown width at the study site; transpiration rates varied by plant and by season. This study encompassed one below-average (2022; 278 mm) and one above-average (2023; 414 mm) precipitation years. Study results showed that the average water use during the entire period of study was 2.1 L d−1 for Plant 1 and 5.0 L d−1 for Plant 2. During the dry year, maximum transpiration was observed during the summer (Plant 1 = 4.8 L d−1; Plant 2 = 11.1 L d−1). For the wet year, both plants showed maximum transpiration levels at the end of the recording period in mid-May (Plant 1 = 9.6 L d−1; Plant 2 = 8.6 L d−1). The highest seasonal transpiration of both plants occurred in summer (2.87 L d−1), whereas the lowest transpiration was obtained in winter (0.21 L d−1). For all seasons but winter, soil moisture (SM), soil temperature (ST), and vapor pressure deficit (VPD) variables generally showed positive correlations with transpiration. Transpiration rates decreased in the summer of 2022 as the surface soil gradually dried. The two plants’ most significant water uptake differences were obtained during the dry year. It is possible that the larger stem diameter of plant 2 may have contributed to its higher transpiration rates during times of limited water availability. The study results add to the understanding of water use by sagebrush and its potential impact on the water balance of cool-climate rangeland ecosystems. The findings also highlight the sensitivity of sagebrush to variations in seasonal soil moisture availability, soil temperature, and vapor pressure deficit. Future research should involve studying the combined effects of water use by various dominant vegetation species and its effects on the water budget at the watershed scale. Full article
