ABSTRACT This paper explores the suitability and advantages of combining trenching technique with geophysical surveys [ground penetrating radar (GPR) electrical resistivity tomography (ERT)] for sinkhole characterization in a mantled karst area. The approach is applied to two active sinkholes concealed by anthropogenic deposits formed contrasting subsidence mechanisms; collapse sagging. ERT section acquired across images clayey fill depression as an obvious low area, showing approximate...
The active lateral spread of the Peracalç Range (Spanish Pyrenees) has developed on a Cretaceous limestone sequence around 250 m thick, underlain by tectonically thickened (∼2.5 km) Triassic halite-bearing evaporites and clays. Outward expansion ductile deformation probably halokinesis toward debuttressed unloaded front range been accommodated in overlying cap rock through development striking horst graben morphostructure. Fault scarps show anomalously high height to length ratios (aspect...
A historical series of aerial photographs spanning more than 70 years (1945–2018) revealed that natural acid rock drainage (ARD) has experienced an intensification in the Noguera de Vallferrera alpine catchment (Central Pyrenees) due to climate change during last decade. ARD manifests by precipitation whitish aluminum-compounds strikingly cover beds some gullies and streams high-mountain catchments. The total length affected increased from ca. 5 km (1945) 35 (2018). Up 68 water samples were...
Abstract This work illustrates the practicality of investigating sinkholes integrating data gathered by ground penetrating radar (GPR), electrical resistivity imaging (ERI) and trenching or direct logging subsidence‐affected sediments in combination with retrodeformation analysis. mutidisciplinary approach has been tested a large paleosinkhole developed during deposition Quaternary terrace on salt‐bearing evaporites. The subsidence structure, exposed an artificial excavation, is located next...
Abstract Coastal groundwater discharge (CGD) plays an important role in coastal hydrogeological systems as they are a water resource that needs to be managed, particularly wetland areas. Despite its importance, identifying and monitoring CGD often presents physical logistical constraints, restraining the application of more traditional submarine surveying techniques. Here we investigate capability electrical resistivity imaging (ERI) Peníscola (Mediterranean coast, Spain). ERI made it...
Abstract Intensive pumping in urban coastal areas is a common threat to water resource quality due seawater intrusion. In those where subsurface resources are not usually used for human consumption or irrigation, intensive associated with other activities like the lowering of table necessary support underground structures and building foundations. This activity also increases likelihood soil settlement that affects stability corrosion concrete groundwater salinity. Under these circumstances,...
