“…Sinkholes are caused by subsurface dissolution and the consequent deformation and/or internal erosion of the overlying sediments. Detailed descriptions of the dissolution and subsidence processes in the study area can be found in Gutiérrez et al (2008), Galve et al (2009) and Acero et al (2015).…”

“…There is a significant number of points with LOS displacement rates below −2 mm yr −1 between 1500 and 2700 m in Profile 1. In this sector, the railways run across subdued sinkholes recognized in old aerial photographs and expressed in cuttings as deformed Quaternary alluvium (Simón et al, 1998(Simón et al, , 2003Galve et al, 2009). The sinkhole cluster comprises a large diffuse-edged depression and several smaller subcircular sinkholes (Fig.…”

Abstract. Subsidence was measured for the first time on railway tracks in the central sector of Ebro Valley (NE Spain) using Differential Synthetic Aperture Radar Interferometry (DInSAR) techniques. This area is affected by evaporite karst and the analysed railway corridors traverse active sinkholes that produce deformations in these infrastructures. One of the railway tracks affected by slight settlements is the Madrid-Barcelona high-speed line, a form of transport infrastructure highly vulnerable to ground deformation processes. Our analysis based on DInSAR measurements and geomorphological surveys indicates that this line shows dissolution-induced subsidence and compaction of anthropogenic deposits (infills and embankments). Significant sinkhole-related subsidence was also measured by DInSAR techniques on the Castejón-Zaragoza conventional railway line. This study demonstrates that DInSAR velocity maps, coupled with detailed geomorphological surveys, may help in the identification of the railway track sections that are affected by active subsidence.

“…The city of Zaragoza in Spain has a population of about 700,000 people, making it one of the largest urban areas affected by gypsum and other evaporite dissolution problems (Gutiérrez et al, 2007(Gutiérrez et al, , 2008cGalve et al, 2009a). Sinkholes here are a major constraint on development; they have collapsed buildings, affected roads, and caused the derailment of a train.…”

“…These features can be mapped producing an inventory of items such as dolines, evidence of subsidence and building damage (Gutiérrez and Cooper, 2002;Nisio et al, 2007;Farrant and Cooper 2008;Cooper, 2008a and b;Galve et al, 2009a). Analysis of the spatial and temporal distribution of the features and the controlling factors can then permit the designation of planning control areas ( Figure 5).…”

“…Field surveying is indispensable and verbal information from farmers, residents and local government officials can add considerably to the data on subsidence features. A complete karst inventory including subsidence features gives an indication of the spatial distribution and severity of the problem (Cooper, 1998;Galve et al, 2009a). This type of information can then be analyzed with respect to other parameters using GIS techniques to produce susceptibility and hazard models (Galve et al, 2008(Galve et al, , 2009b.…”

Synopsis/Abstract 153 wordsGypsum dissolves rapidly underground and at the surface forming gypsum karst features that include caves, subsidence areas and sinkholes. Mapping these landforms, understanding the gypsum karst and local hydrogeology, and producing sinkhole susceptibility and hazard maps are crucial for development and public safety. Situations that change the local hydrogeology, such as dams, water abstraction or injection/drainage, can accelerate dissolution and subsidence processes increasing the severity of the problems; dams and canals built on gypsum karst can leak or fail catastrophically. Gypsum karst problems can be mitigated by careful surveying and scientific investigation followed by phased preventive planning, ground investigation and construction incorporating sinkhole-proof designs. Towns and cities, including parts of Paris (France), Dzerzhinksk (Russia), Madrid and Zaragoza (Spain), Birzai (Lithuania) and Ripon and Darlington (UK), are developed on such ground requiring local planning guidelines and special construction methods. Roads, railways, pipelines and bridges are particularly vulnerable to such subsidence and require special consideration.

Sinkholes commonly form by subsurface dissolution cavities that collapse after the overlying layers become mechanically unsupported. Sinkholes along the Dead Sea shorelines are preceded by, associated with, and followed by gradual surface subsidence that accompanies the cavities' growth. We exploit satellite radar interferometry (interferometric synthetic aperture radar) to resolve temporal and spatial relationships between gradual subsidence and sinkhole collapse. The geometry of the deflating cavity roof is determined by elastic inverse modeling of the surface displacements. A Coulomb failure stress criterion is applied to calculate the stress field induced by the deflating cavity at the ground surface. We find that the induced stress field favors generation of sinkholes at the perimeters of the subsiding areas rather than at their centers, in agreement with field observations, providing important information for sinkhole hazard assessment. Further, our analysis suggests that short‐term deformation in consolidated gravel layers at shallow depths could be approximated by simple elastic modeling.
