Special Issue Information

Dear Colleagues,

Civil structures and infrastructure are continuously subjected to natural hazards, including seismic activity, flooding, and wind, which may cause degradation of the structural performance and even lead to collapse. Currently, decisions related to maintenance and emergency management mainly consist of heuristic methods relying on the results of visual inspections and expert opinion. In recent years, infrastructure asset managers have been promoting permanent static and dynamic monitoring systems. Information acquired by these systems, such as loads and environmental actions, structural performance, and deterioration level, can reduce uncertainties in estimating the serviceability level of structures. With this information, asset agencies may implement optimal structural management decisions guaranteeing an adequate level of structural safety. Although structural health monitoring (SHM) has been gaining increasing interest in the research community, several aspects need further investigation.

This Special Issue invites high-quality contributions addressing the current state of the art, recent developments, and future perspectives in SHM in hazardous environments. The topics of interest include but are not limited to:

  • Monitoring under hydro-geological hazard, e.g., considering flood, scour, and landslides;
  • Seismic SHM;
  • The influence of soil-structure interaction in SHM;
  • Emerging technologies for monitoring structures, infrastructures, and ground motion, e.g., unmanned aerial vehicles (UAV) and satellites;
  • Informed structural management under multiple natural hazards.

The authors can contribute by presenting both theoretical papers and case studies.

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.

Trenched pipelines may experience significant lateral displacement due to natural geohazards such as strike slip-fault movements, landslides, etc. Using pre-excavated soil to backfill trenches is a cost-effective option to protect pipelines against large deformations. These backfilling materials are heavily remolded and therefore softer than the native ground. Therefore, the shear strength difference between the backfill and native ground may affect the pipeline–backfill–trench interaction and the failure mechanism of the surrounding soil. By assuming a simplified uniform soil domain, the influence of softer pre-excavated backfilling material on the pipeline–backfill–trench interaction is neglected in the analytical methods that are usually used in the structural health monitoring of buried pipelines. In this study, the effects of trenching and backfilling were incorporated into an analytical solution for a fast assessment of the pipeline response at the early stages of engineering design projects and structural health monitoring. In comparison with other methods, this methodology provides a convenient and efficient method for computing pipeline strain and deflection curves in geohazardous regions. Full article

Shipwrecks are important cultural heritage sites offshore. In many instances, given their often long-term emplacement on the seafloor, they offer natural laboratories to study complex interactions between human-induced obstacles and seabed dynamics. Such interactions and induced sediment mobility also pose significant threats to offshore engineering infrastructure, such as turbine monopile foundations. Traditional methods can struggle to capture the nuance of these processes, with real-world surveys measuring effects only after installation, and laboratory models suffering from scale-down inaccuracies. Computational fluid dynamics (CFD) modelling offers an effective means of investigating the effects of obstacles on seabed dynamics, and by using shipwrecks as proxies for infrastructure, it can utilize long-term datasets to verify its predictions. In this study, high-resolution temporal bathymetric data were used in, and to verify, CFD modelling to investigate the interactions between hydro- and sediment dynamics at a shipwreck site in a tidally dominated wreck site. From this comparison, simulations of bed shear stress and scalar transport correlate well with known areas of erosion and deposition, serving as a basis for future scour prediction studies and creating effective tools in offshore renewable infrastructure planning and de-risking.
