Dear Colleagues,

The exploitation of Earth observation (EO) methodologies presently represents a common practice in the scientific community. Of great interest is the development and application of remote sensing techniques for the detection of environmental changes of coastal regions, which are the location of large population centers; have multiple uses, needs and opportunities; and are particularly exposed to extreme events and climate change. Coastal zones are thus essential for the socio-economic well-being of many nations. The combined effects of sea level rise (SLR), tidal evolution, modulated ocean currents and extreme events can have numerous impacts on coastal, river delta, and inland water zones. Among the impacted sectors is water management, which in turn leads to cascading and unpredictable impacts on other sectors.

Remote sensing (RS) technologies can measure and map the long-term evolution of coastal and deltaic environments, providing updated information on environmental variations, assessing hazards and risks, and understanding the relevant mechanisms. The use of optical, SAR, and hyper-spectral data products are fostered. Many new RS satellite programs are being scheduled and deployed, and many new methods are being developed in concert. Constellations of satellite sensors working from microwave to optical wavelengths are systematically used to monitor the changes. In the application of newly developed RS technologies, emphasis has been placed on studying various disaster risks that affect coastal, river delta, and megacity areas, and their cascading and unpredictable impacts. The current stage of remote sensing approaches employed to study coastal and delta river regions will be demonstrated.

This Special Issue is open to all researchers. Papers are solicited on the following general themes:

• Study of ground deformation in coastal/deltaic regions with conventional and novel remote sensing approaches;
• Microwave remote sensing applications: new instruments and acquisition modes;
• The potential of new-generation SAR instruments onboard principal spaceborne platforms;
• Development of novel change detection methods, with emphasis on urbanized areas;
• Study of the interactions between ocean currents and coasts, such as coastal erosion, using high-resolution optical and radar satellite images;
• Assessing sea-level-rise (SLR), tidal evolution, and hydrogeological risks in urban coastal areas;
• Study the interactions between inland water bodies and its connecting rivers;
• Study atmosphere/surface interactions;
• Development of methods to integrate satellite- and ground-based radar systems to monitor public infrastructures;
• Development of interactive maps of coastal, urban, and inland zones susceptible to primary and secondary risks via GIS.

Original research articles and review papers are expected.

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. Remote Sensing 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 2700 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.
