Environmentally Sustainable and Water Engineering: Arid and Semiarid Hydrology and Sediment Transport

Dear Colleagues,

The landscapes from semiarid and arid environments can change and are frequently in an inflection point for the development of the environment, even more from a climate change perspective. Soils, plants, and water are connected in arid and semiarid environments. In this sense, the rainfall patterns and their consequences generate flow in hillslopes, and the sediment flux consists of bedload and suspended sediment on the fluvial systems, drawing and building the landscape from the geomorphologic past to the present and the possible new environments. The linkage between the geomorphologic past and the current landscape can be established through the transport phenomenon on watershed hillslopes and the fluvial sediment transport rates, as well as the lateral connectivity of the water surface and sediment discharge through hydrologic parameters. Therefore, the connectivity between the transport phenomenon in the watershed hillslopes and sediment transport rates may link issues such as lateral flow to natural resistance soils to the water surface, which address all soil erodibility of the watershed working together against the surface flow and the soil cover promoted by crops (soil–vegetation complex) that generates resistance/impedance to lateral sediment transport (bedload and suspended sediment) delivered at the drainage system, and in the significant watershed channel (river). In this direction, water and sediment engineering tools can help us to understand and work toward a sustainable arid and semiarid world. We invite all researchers working with sediment transport and hydrology in arid and semiarid environments to submit scientific articles to this Special Issue of the Sustainability journal.

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. Sustainability 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 2400 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.
