New Insights into Sea Level Dynamics and Coastal Erosion

Dear Colleagues,

Coastal storms and sea-level rise are widely recognized as increasingly severe threats to coastal communities and ecosystems. Intensive scientific studies on sea-level dynamics and coastal geomorphology are revealing complex sedimentologic, vegetative, and anthropogenic responses that vary over space and time. However, tipping points, thresholds, and non-linearities in the evolution of coastal systems continue to cloud our ability to forecast evolution in these dynamic settings. To improve our understanding of coupled natural-human dynamics on coasts, it becomes attractive to develop conceptual frameworks, numerical models, and diverse observational approaches. Concomitantly, enormous volumes of data from Earth observations, in situ sensors, and Uncrewed Autonomous Systems (UAS) are proving valuable for data-based analyses and validation of modeling and simulation. There is a need for the synthesis of short- and long-term processes for sustainable coastal development, which presents a demand and opportunity to bring together the current theory, practice, and methodological advances in coastal systems.

This Special Issue seeks to collect and share relevant advances and insights into coastal geomorphic systems undergoing sea-level rise. Potential topics in the context of coastal landforms and sea-level change include, but are not limited to, the following:

• Coastal paleolandform evolution and paleotempestology along coasts;
• Vertical land motion effects on coastal landforms and processes;
• Multi-modal observations of coastal landform change;
• Regime shifts among riverine–estuarine–marine processes;
• Erosion, transportation, and depositional processes;
• Morphodynamic modeling of coastal landform responses;
• Natural and nature-based infrastructure and coastal landform changes;
• Long-term efficacy of living shorelines with sea-level change;
• Sustainable development in coastal systems undergoing sea-level change.

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.
