Caracterización de acuíferos mediante testificación geofísica e imágenes 3D en los sondeos de investigación Almera-1 y Almera-2, en el entorno urbano de la ciudad de Barcelona; Geophysical characterization of aquifers, in Almera-1 and Almera-2 boreholes, in urban area in Barcelona

Abstract

Logging, borehole imaging and monitoring carried out in the scientific boreholes Almera-1 and Almera-2 in the Pedralbes campus of the University of Barcelona has allowed us to identify three preferential groundwater flow paths. Geophysical logging data combined with groundwater monitoring levels allowed us to identify three high permeable zones in the boreholes. Logging data combined with core analysis were used to characterize the aquifers lithology and petrophysical properties. We compared the groundwater measured levels and the rainfall in the area to identify and characterize aquifer dynamics and potential relationships between the variations in groundwater levels and the rainfalls.
