About this Research Topic

Background

With the rapid urbanization of cities around the world, water security, flood control, and urban hydro-environment have become important tasks to tackle. The majority of large to megacities are located at delta regions surrounded by river networks, due to their historical development. They are not only threatened by floods from upstream river basins but also face the problem of urban hydro-environment governance. Fast urbanization causes interference and division of the river system and impedes its hydrodynamic potential, which is the primary culprit for flooding, pollutants, and sediment deposition. Consequently, water security and environmental problems are major issues in regard to sustainable urban development.

This Research Topic aims to minimize the effects of urban development on the fluvial and freshwater system. This can be achieved through a collection of expert studies concerning the urban river network, hydrodynamics, hydro-environment, and sediment transport.

In recent years, urban hydrological and hydrodynamic models have generated tremendous interest from scholars and practitioners all over the globe. These can be widely applied to urban flood management, water pollution mitigation studies, urban watercourse behavioral sciences, and river restoration efforts. This list demonstrates the crucial role of these models and how they benefit a wide range of communities. Although this collection targets the latest research in theoretical and numerical fields, interesting experimental studies are also welcome.

In summary, this Research Topic welcomes high-quality submissions with an aim to produce a collection targeted to achieve a safer, healthier, and better urban-fluvial environment. We are looking for, but not limited to, innovative theories, advanced technologies, and application examples in this targeted field of study.

Potential themes include:
• Urbanization processes affecting the fluvial environment.
• How river networks have been altered and their responsive characteristics.
• Hydrological and hydrodynamic models which demonstrate urban hydrological advances.
• Hydro-environmental research explaining how to mitigate the urban influence on the fluvial system.
• Sustainable cities implementation of fluvial management and green networks.

Keywords: Urbanization, river network, hydrodynamics, hydro-environment, sustainability, fluvial management, urban flood management, water pollution mitigation studies, river restoration efforts, urban watercourse behavioural sciences

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

• What is a Research Topic?

  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.

• Why does Frontiers publish Research Topics? 

  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.

• Why are Research Topics important for journals?

  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.

• How do we ensure the quality of articles within Research Topics?

  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.

• What are the benefits of publishing my article in a Research Topic?

  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.

   
• What types of articles can be published in a Research Topic?

  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.
