Special Issue Information

Dear Colleagues,

River floodplains are some of the most biologically diverse and productive ecosystems on earth. Fluvial dynamics associated with flooding play a major role in maintaining a diversity of lotic, lentic, and semi-aquatic habitat types across space and time. Further, a river’s lateral connectivity with its floodplain supports hydrodynamic, geomorphic, and ecological processes that sustain diverse ecosystems while providing ecosystem services such as floodwave attenuation and improved water quality. In spite of the important functions provided by river floodplains, humans have dramatically modified floodplain features and the supporting natural flow regimes for nearly every major river in the temperate zone, and this has been accompanied by a loss in biodiversity and the underlying hydrologic, geomorphic, and ecological functionality. To address this challenge, governments around the world have invested heavily in restoring floodplain systems, using both direct and indirect methods. Direct methods include mechanical interventions to stabilize, destabilize, reconnect, or otherwise construct desired floodplain forms, along with clearing of invasive vegetation species, levee setbacks, and even removal of infrastructure. Indirect approaches are focused on restoring components of the natural flow and sediment regimes along with other watershed and riparian corridor management approaches. This Special Issue aims to advance understanding of fundamental and practical elements of river floodplain restoration approaches including advancements in restoration frameworks, design approaches, numerical models, applications of remote sensing, significant case studies, and other relevant research. We are particularly interested in retrospective articles that critique and advance understanding of floodplain restoration approaches based on historical projects.

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 papers will be 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. Water is an international peer-reviewed open access semimonthly 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 2000 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.

Nutrient loads in fresh and coastal waters continue to lead to harmful algal blooms across the globe. Historically, floodplains—low-lying areas adjacent to streams and rivers that become inundated during high-flow events—would have been nutrient deposition and/or removal sites within riparian corridors, but many floodplains have been developed and/or disconnected. This review synthesizes literature and data available from field studies quantifying nitrogen (N) and phosphorus (P) removal within floodplains across North America and Europe to determine how effective floodplain restoration is at removing nutrients. The mean removal of nitrate-N (NO3-N), the primary form of N in floodplain studies, was 200 (SD = 198) kg-N ha−1 year−1, and of total or particulate P was 21.0 (SD = 31.4) kg-P ha−1 year−1. Based on the literature, more effective designs of restored floodplains should include optimal hydraulic load, permanent wetlands, geomorphic diversity, and dense vegetation. Floodplain restorations along waterways with higher nutrient concentrations could lead to a more effective investment for nutrient removal. Overall, restoring and reconnecting floodplains throughout watersheds is a viable and effective means of removing nutrients while also restoring the many other benefits that floodplains provide.
