Sediment Movement, Sustainable Water Conservancy and Water Transport

Dear Colleagues, 

In recent decades, sediment transport has been a hot issue for sedimentologists to study. Especially in water conservancy and water transportation engineering, the changes in the topography of rivers, lakes, and estuaries caused by sediment movement are of great interest. Human activities have an increasingly important influence on the sediment movement of watersheds and rivers. The water resource development in large river terraces has greatly changed the water and sediment movement patterns in the upstream and downstream dams. Thus, increasing anthropogenic interventions affect rivers' hydrological processes and sediment dynamics and threaten the habitat structure and aquatic ecosystem diversity. An improved understanding of hydrological, hydrodynamic, and sediment transport and morphological processes is needed to address these challenges. Moreover, there is an urgent need to improve predictive models to increase the prediction accuracy of streambed evolution.

This Special Issue aims to bring together recent theoretical and applied research on a wide range of topics related to flow and water quality processes in modeling river and coastal watershed systems from the catchment to the coast, for example, innovative studies that use new monitoring, modeling, or analytical techniques to investigate the reciprocal response mechanisms of sediment movement under complex conditions a well as hydraulic engineering and water transport engineering applications. This Special Issue of Sustainability calls for innovative research papers on topics including, but not limited to, the following:

(1) Impacts of runoff and sediment transport variations;
(2) Sediment budget and sediment yields;
(3) Riverbed evolutionary process;
(4) Impacts of dams on the upstream and downstream hydrological conditions;
(5) Impacts of hydrological changes on morphological changes;
(6) Movement characteristics of suspended sediment and bed load sediment;
(7) Spatiotemporal morphological changes and the associated influences;
(8) Impacts of morphological changes on hydraulic structure and flood risk;
(8) Impacts of morphological changes on waterway maintenance;
(9) Variations in fluvial processes;
(10) Understanding grain size distribution changes and the associated morphological response;
(11) Natural and anthropogenic impacts on the morphological changes;
(12) River morphology and river ecosystem restoration;
(13) Riverbed incision, bank erosion, and coastal erosion;
(14) Improving the accuracy of riverbed evolution prediction;
(15) Quantifying hydro-morphological responses to the multi-objective optimal reservoir scheduling.

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.
