Special Issue Information

Dear Colleagues,

As the consequence of global warming, the frequency, intensity, and duration of climate extremes have increased across the globe, and are projected to increase in the future. For example, heatwave records in European in 2003 and Russia in 2010 demonstrated that extreme high temperatures accompanied by droughts are among the most serious natural disasters and are becoming the leading causes of vegetation mortality and water scarcity.

However, the eco-hydrological processes underlying climate extremes are extremely complex. For instance, summer droughts and heatwaves can directly amplify evapotranspiration, leading to reduced soil moisture and runoff, thus stressing vegetation growth. Anomalously warm springs may extend vegetation activity periods, adding pressure to water resource utilization during the summer. In fact, a wide variety of extreme climate event types, including rain storms, extreme colds, droughts, heatwaves, etc., are happening with diverse spatial and temporal distributions. Moreover, compound extreme events, such as simultaneous droughts and heatwaves, lack comprehensive consideration in terms of their impact on regional ecological hydrological processes.

The aim of this Special Issue is to promote research on eco-hydrological processes under extreme climatic conditions, contributing to a better understanding of the current field and providing data support for policy-making.

This Special Issue will welcome manuscripts that link the following themes:

  • ecological hydrological monitoring;
  • active or passive remote sensing methods;
  • distributed hydrological modelling;
  • software tool development for data collection and processing.

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

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.

Droughts impact the water cycle, ecological balance, and socio-economic development in various regions around the world. The Orinoco River Basin is a region highly susceptible to droughts. The basin supports diverse ecosystems and supplies valuable resources to local communities. We assess the spatiotemporal patterns and impacts of droughts in the basin using remote sensing data and surface observations. We use monthly precipitation (P), air temperature near the surface (T2M), enhanced vegetation index (EVI) derived from Earth observations, and average daily flow (Q) data to quantify drought characteristics and impacts. We also investigated the association between drought and global warming by correlating the drought intensity and the percentage of dry area with sea surface temperature (SST) anomalies in the Pacific (Niño 3.4 index), Atlantic (North Atlantic Index [NATL]), and South Atlantic Index [SATL]) oceans. We evaluate the modulating effect of droughts on the hydrological regime of the most relevant tributaries by calculating the trend and significance of the regional standardized precipitation index (SPI) and percentage area affected by dry conditions. El Niño events worsen the region’s drought conditions (SPI vs. Niño 3.4 index, r = −0.221), while Atlantic SST variability has less influence on the basin’s precipitation regime (SPI vs. NATL and SATL, r = 0.117 and −0.045, respectively). We also found that long-term surface warming trends aggravate drought conditions (SPI vs. T2M anomalies, r = −0.473), but vegetation greenness increases despite high surface temperatures (SPI vs. EVI anomalies, r = 0.284). We emphasize the irregular spatial-temporal patterns of droughts in the region and their profound effects on the ecological flow of rivers during prolonged hydrological droughts. This approach provides crucial insights into potential implications for water availability, agricultural productivity, and overall ecosystem health. Our study underlines the urgent need for adaptive management strategies to mitigate the adverse effects of droughts on ecosystems and human populations. The insights derived from our study have practical implications for developing strategies to address the impacts of droughts and ensure the protection of this ecologically significant region.
