Background

Environmental hydrology stands at the forefront of scientific efforts to address urgent global challenges such as climate change, shifting land-use patterns, and the intensifying impact of human activity on water systems. These forces increasingly drive complex issues, including agricultural non-point source pollution, ecosystem degradation, and rampant water scarcity across continental and regional scales. While traditional approaches in monitoring and modeling have provided foundational insights into hydrological processes and management, rapid advances in technology and data science now offer the potential to revolutionize how we understand, predict, and manage environmental water resources. However, knowledge gaps remain regarding the effective integration of emerging monitoring tools, advanced models, and decision-support frameworks—especially in translating scientific advances to scalable, actionable solutions.



Recent years have seen significant progress in environmental hydrology, spurred by breakthroughs in sensor networks, Internet-of-Things (IoT) platforms, and real-time remote sensing using UAVs and satellites. At the same time, hydrological modeling is evolving beyond process-based frameworks to leverage artificial intelligence, machine learning, Large Language Models (LLMs), and Digital Twin technologies. Integrated data streams and advanced analytical methods are generating unprecedented opportunities to support adaptive management, foster participatory stakeholder processes, and inform evidence-based policies. Despite these innovations, major challenges persist in closing the gap between technological capability, ecological insight, and practical implementation on the ground.



This Research Topic aims to catalyze and disseminate novel research that advances the full continuum of environmental hydrology, from next-generation monitoring to innovative modeling approaches and the development of decision-support systems for real-world application. By drawing on interdisciplinary advances, this initiative seeks to highlight how hydrological understanding can be harnessed to foster adaptive, resilient, and sustainable water management in the face of mounting environmental pressures.



Covering the full range of scales and settings, the scope of this Research Topic is limited to studies that demonstrate innovation in monitoring, modeling, and informed hydrological management with clear relevance to contemporary environmental challenges. We welcome articles that address, but are not limited to, the following themes:



• Breakthroughs in environmental hydrology and water system understanding



• Development and field application of advanced hydrological models



• Novel monitoring technologies, including IoT, UAVs, and real-time remote sensing



• Integration of AI, machine learning, and LLMs in hydrological science

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
