SAR Applications in Engineering Geology and Structural Engineering

Dear Colleagues,

The scientific community can take advantage in terms of knowledge from InSAR and DInSAR products such as single interferograms and time series, thanks to the increasing availability of satellite SAR data (ERS, ENVISAT, COSMO-SkyMed, ALOS and TerraSAR-X, Sentinel-1a/b, etc.). Moreover, the progressive potential of these kinds of sensors in terms of spatial resolution; revisiting time, which is the prerogative of the orbiting constellation; and the different wavelengths, make the available products more accurate and suitable for using in a broad spectrum of engineering geology and structural engineering. Furthermore, the possibility to integrate the classic interpretation techniques, which stem from classic methods for producing DInSAR products, make it possible to grow new, strategic, worldwide research fields. In particular, the multi-temporal interferometric synthetic aperture radar (MT-InSAR) is a monitoring technique capable of extracting line of sight (LOS) cumulative surface displacement measurements with millimeter accuracy. Several improvements in the techniques and datasets quality have led to more effective, near real-time assessment and responses, and a greater ability to constrain dynamically changing physical processes. Overall, the availability of new constellations of synthetic aperture radar (SAR) sensors is leading to important advances in engineering geology and structural engineering. These constellations offer the advantage of reduced revisit times, providing low-latency data that enable analysis that can identify structural instability and dynamic deformation processes.

This Special Issue focuses on new applications jointly exploiting differential techniques, bridging the gaps between remote-sensing space-borne observations in engineering geology and structural engineering.

We are inviting submissions associated with the following:

• Landslides
• Bridges
• Dams and levees
• Sinkholes
• Infrastructure
• Natural and anthropic subsidence
• Anthropogenic hazards
• Technological disasters
• Earthquakes

We seek studies involving interferometric SAR or pixel-offset techniques. We also invite submissions that use SAR data to improve rapid responses and provide an early warning for anthropogenic disasters. We invite kilometer- to continental-scale studies relying either on recently acquired data or on a compilation of archived data acquired from satellite, airplane, or ground-based radar systems.

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. Geosciences 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 1800 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.
