Non‐invasive surveys to assess animal burrows as potential causes of levee instability

Journal of Flood Risk Management, Volume 16, Issue 4, December 2023., 2023
Abstract Animal activities threaten levee stability, especially during flood events, increasing levee failure risk. Indeed, while dens alter hydraulically‐induced failure mechanisms, it is difficult to locate them and to know in advance if critical conditions may be reached.

Kinematic Evolution of a Large Paraglacial Landslide in the Barry Arm Fjord of Alaska

Journal of Geophysical Research: Earth Surface, Volume 128, Issue 11, November 2023., 2023
Abstract Our warming climate is adversely affecting cryospheric landscapes via glacial retreat, permafrost degradation, and associated slope destabilization. In Prince William Sound, Alaska, the rapid retreat of Barry Glacier has destabilized the slopes flanking the glacier, resulting in numerous landslides. The largest of these landslides (∼500 Mm3 in

Comprehensive geophysical prospection of the Roman and late antique city of Pollentia (Alcúdia, Mallorca, Spain)

Archaeological Prospection, Volume 30, Issue 4, Page 411-427, October/December 2023., 2023
Abstract An extensive magnetic survey has been carried out on a large part of the Roman and late antique city of Pollentia (Alcúdia, Mallorca, Spain), combined with ground penetrating radar (GPR) and electric resistivity imaging (ER Imaging) to obtain data for a better understanding of the ancient city.

Unprecedented Observation of Hourly Rock Glacier Velocity With Ground‐Based SAR

Geophysical Research Letters, Volume 50, Issue 9, 16 May 2023., 2023
Abstract The kinematic acceleration of rock glaciers observed in recent decades shows that the behavior of these landforms is related to climate change. Velocity variations on yearly to seasonal time scales are frequently investigated, but velocity changes measured on shorter time scales (i.e., on hourly resolutions) are as yet poorly investigated.

Load‐deformation behavior of locally corroded reinforced concrete retaining wall segments: Experimental results

Structural Concrete, Volume 24, Issue 1, Page 288-317, February 2023., 2023
Abstract Local reinforcement corrosion damage reduces the load‐bearing capacity of reinforced concrete structures and, even more severely, their deformation capacity. This problem is of particular concern for cantilever retaining walls, whose loading is dominated by earth pressure and hence, depends on the wall deformations.

Seismic Response Analysis of Secondary Lining Polymer Grouting Debonding Repair for Tunnel Construction Based on Parameter Inversion

Advances in Civil Engineering, Volume 2023, Issue 1, 2023., 2023
The void phenomenon behind the tunnel lining has become the main cause of tunnel disease, easily triggering tunnel lining structure damage, shedding, water seepage, and other diseases that seriously threaten the normal operation of the tunnel. The void area behind the lining seriously reduces the seismic capacity of the tunnel.
