Beyond the Channel—Investigating Processes at Crucial Fluvial Interfaces

Dear Colleagues,

Rivers are cradles of human civilization, and continuously provide critical ecosystem services such as water supply, irrigation, navigation, habitat, etc, to human society. Due to climate change and anthropogenic impacts, many rivers worldwide have experienced regime shifts in fluvial processes, which often affects their health and delivery of services. Complementary to flow and sediment regimes in the main channel, several processes of paramount importance are occurring at the environment interfaces such as the air-water, water-sediment, water-vegetation, and freshwater-seawater interfaces.

The overall goal of this Special Issue of Geosciences is to explore the processes at these crucial interfaces of the fluvial environment, that also play important role in river geomorphology and in maintaining the health and functioning of rivers and interfacing ecosystems. For this Special Issue papers reporting theoretical, observational, experimental, and numerical investigations on these processes as well as on their implications for river management and restoration are welcome.

This special issue aims to cover, without being limited to, the following areas:

• gas-transfer at free-surface;
• sediment transport and morphodynamics in streams and rivers;
• hyporheic fluxes;
• flows at river confluences;
• vegetated flows;
• estuarine hydrodynamics and morphodynamics;
• riverine eco-hydraulics.

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. Geosciences 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.
