The bedrock of the Ebro Valley consists of soluble geological formations of evaporites. The subsurface dissolution of these rocks makes this area particularly prone to the development of sinkholes. These show subsidence that causes damage to man-made structures. The article focuss on the subsidence detected along railways that traverse sinkholes. DInSAR analysis may help in the identification of subsiding sectors of railway tracks that may compromise the safety of travellers.
The 2012 Emilia seismic sequence (Italy) caused significant liquefaction-related damage. We used a lidar DTM and the 2012 liquefaction data to (a) perform a geomorphological study of the Po River plain and (b) define the liquefaction susceptibility of the geomorphologic features. Results indicate that fluvial landforms acted as a preferential location for the occurrence of liquefaction. We quantitatively defined a hierarchy in terms of liquefaction susceptibility for an ideal fluvial environment
The proposed methodology aims to simultaneously simulate wave overtopping and the resulting flood in an urban area, with respect to chronology and buildings effect. Based on a downscaling approach, this method uses a time-dependent phase-resolving model to simulate dynamically the flows on a DEM including buildings. Applied to the Johanna storm in Gâvres (France), this method allowed for obtaining very realistic results in terms of water depths and flow velocities at a very high resolution.
A criterion to categorise climate change adaptation frameworks is presented denoting characteristics of three key frameworks established in the literature: scenario–led, decision-centric and vulnerability–led. Applying the criterion, the usability of frameworks is examined in coastal Suffolk. Results indicate adaptation frameworks established in the literature are not utilised in isolation in everyday practice. In reality, hybrid approaches are utilised to overcome aspects of framework weakness.
This review discusses published studies analyzing the atmospheric conditions that induce extreme precipitation over the eastern and western Mediterranean regions. It presents a systematic description of the interlacing role of several atmospheric processes of different scales - local, meso, and synoptic - that enable the development of torrential rains.
This data set contains infrasonic detection bulletin for data recorded between 1 December 2012 and 31 March 2013 by the infrasound array deployed in Ischgl, Austria, and described in the paper. This data set contains all infrasound detections that are used to derive most of the results presented in the manuscript.
The sudden onset of large and erosive debris flows has been observed recently in different catchments in Switzerland, implicating the importance of erosion for debris flow modelling. Therefore, an erosion model was established based on field data (relationship between maximum shear stress and erosion depth and rate) of several debris flows measured at the Illgraben. Erosion model tests at the Spreitgraben showed considerable improvements in runout pattern as well as hydrograph propagation.
A landslide, to the west of Montemurro (southern Italy), has recently caused damage to buildings and other infrastructure in an urbanized area. In this paper, we present the results of a study carried out using field surveys, geognostic investigations and TDR measurements in order to reconstruct the stratigraphy of the sediments involved and to further understand the geological and geomorphological context of the slope.
