Se realiza un análisis por prospección geofísica mediante tomografía eléctrica (ERT, electrical resistivity tomography) en el abrigo de Sopeña (Asturias) y su zona inmediata. El abrigo contiene un interesante yacimiento del Paleolítico Medio superior y Paleolítico Superior inicial, desvelado en un sondeo arqueológico de hasta 3 metros de profundidad sin haber alcanzado la base rocosa. Su entrada actual está protegida por grandes bloques caídos de la cornisa, recubiertos por gruesas coladas estalagmíticas. Esta disposición posiblemente atestigua una posición original de la zona de ocupación humana más interna, dentro de una cueva de mayores dimensiones. Mediante este análisis hemos localizado varios posibles rellenos sedimentarios a cierta profundidad en el exterior del abrigo. Se abre así la posibilidad de muestrear en un futuro esos rellenos, en busca de posibles niveles de ocupación más antiguos.

The Difference

Water percolation through infiltration ponds is creating significant synergies for the broad adoption of water reuse as an additional non-conventional water supply. Despite the apparent simplicity of the soil aquifer treatment (SAT) approaches, the complexity of site-specific hydrogeological conditions and the processes occurring at various scales require an exhaustive understanding of the system’s response. The non-saturated zone and underlying aquifers cannot be considered as a black box, nor accept its characterization from few boreholes not well distributed over the area to be investigated. Electrical resistivity tomography (ERT) is a non-invasive technology, highly responsive to geological heterogeneities that has demonstrated useful to provide the detailed subsurface information required for groundwater modeling. The relationships between the electrical resistivity of the alluvial sediments and the bedrock and the difference in salinity of groundwater highlight the potential of geophysical methods over other more costly subsurface exploration techniques. The results of our research show that ERT coupled with implicit modeling tools provides information that can significantly help to identify aquifer geometry and characterize the saltwater intrusion of shallow alluvial aquifers. The proposed approaches could improve the reliability of groundwater models and the commitment of stakeholders to the benefits of SAT procedures.
