This contribution analyses the processes involved in the generation of sinkholes from the
study of paleokarst features exposed in four Spanish Tertiary basins. Bedrock strata are …

Sinkholes usually have a higher probability of occurrence and a greater genetic diversity in
evaporite terrains than in carbonate karst areas. This is because evaporites have a higher …

A geophysical survey routine is proposed to detect underground cavities and dolines; it is
based on the sequential application of magnetic, low-frequency ground penetrating radar …

Detection, forecasting, early warning, and effective monitoring are key aspects for the
delimitation of sinkhole-prone areas and for susceptibility assessment and risk mitigation. To …

In Segovia Province, Spain, there are numerous carbonate rock outcrops that are affected by
karstification processes, in which there are numerous galleries, caves and sinkholes. This is …

Multiple sinkhole susceptibility models have been generated in three study areas of the Ebro
Valley evaporite karst (NE Spain) applying different methods (nearest neighbour distance …

This paper explores the suitability and advantages of combining the trenching technique
with geophysical surveys [ground penetrating radar (GPR) and electrical resistivity …

In Spain, evaporite outcrops cover approximately 7% of the total area of the country. Most of
the evaporitic formations are made up of Ca-sulfates (gypsum/anhydrite) or Ca-sulfates and …

A detailed sinkhole map has been produced in a stretch of the Ebro Valley (40.8 km2)
including the western sector of Zaragoza city (NE Spain). During the last few decades …

Abstract Differential Interferometric Synthetic Aperture Radar (DInSAR) has been applied to
detect and measure ground deformation in a stretch of the Ebro River valley (Spain) …
