Dear Colleagues,

Climate changes and global warming are expected to significantly impact coastal water systems. Changes in air and water temperatures, as well as sea level rise are expected to greatly influence coastal water dynamics and ecosystems. In particular, sea level rise will affect the exchange between ocean and coastal waters, inducing changes in lagoon and estuarine circulations, which, in turn, can affect the transport of dissolved and suspended matter, the nutrient and sediment budgets, and, ultimately, the biogeochemical processes inside those systems.

Due to the interconnection between these processes, integrated and multidisciplinary approaches are necessary to forecast the evolution of these coastal systems. This requires bringing together specialists from several scientific areas in order to discuss the state-of-the-art of their sciences, including more recent and modern tools, namely numerical and risk assessment models and data management.

This Special Issue aims to contribute to the assessment and quantification of coastal ecosystems status under present and future climates, as well as to indicate the directions needed to manage and mitigate related risks and uncertainties.

It is, therefore, intended to bring together the scientific community from several areas of coastal water science (biologist, geophysicist, climatologist, modelers, engineers, etc.) by inviting contributions focusing on:

• The state-of-the-art of modelling coastal water systems
• The risk assessment tools for the coastal water systems
• The present and the future climates for coastal areas, including meteorological extreme events
• Case studies and scenarios under different forcing: Induced naturally, anthropogenically and/or by climate change
• The global warming impact in coastal systems
• Vulnerability of coastal systems under climate change scenarios

Research articles, review articles, case studies and perspectives dealing with coastal system and the issues related to global changes, including anthropogenic, natural and climate changes, are, therefore, welcome to this Issue. We look forward receiving original contributions.

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. Journal of Marine Science and Engineering is an international peer-reviewed open access monthly 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.
