Special Issue Information
Dear Colleagues,
Over the last century, diminished fluvial sediment supply, combined with high subsidence rates and saltwater intrusion, has contributed to high rates of land loss in the world’s river deltas. On the Mississippi River delta, efforts amounting to USD 50 billion are currently underway to restore and protect this landscape, and a central feature of this effort is the use of large sediment diversions to re-establish the connection between the delta and its fluvial supply of sediments, nutrients, and fresh water. Though it is generally agreed that increasing sediment supply is critical to delta restoration, impacts associated with nutrient and fresh water delivery have raised concerns about diversions related to increased flooding, erosion, eutrophication, and altered salinity regimes. This Special Issue aims to bring together recent studies that examine impacts of sediment, nutrients, and fresh water delivery on the sustainability of coastal wetland ecosystems brought about by river diversions. Topics could include, as they relate to river diversions,
- wetland sediment deposition and accretion;
- erosion;
- impacts of altered salinity, inundation, nutrient, or turbidity regimes on wetland plants, soil dynamics, water quality, and coastal fisheries;
- nuisance flooding.

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 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 2600 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.
