WITHDRAWN Monitoring Groundwater Using Ambient Seismic Noise
Description:
WITHDRAWN The management of groundwater resources forms a crucial component of national policies. Different countries around the world are experiencing crises in groundwater availability as a result of a number of economic, social, and environmental conditions. Therefore, efficient management of groundwater resources is dependent on accurate knowledge and understanding of the behavior and variability of the aquifers. Such knowledge is often lacking or limited to sparse and highly localized information. This study focuses on analyzing ambient seismic noise recorded in two different geological environments: the island of Malta (central Mediterranean) and the Río de la Plata Coastal Plain (Argentina). The latter features partially interconnected coastal aquifers developed in thick sedimentary deposits. In contrast, the Malta hydrogeology is mainly controlled aquifers that occur in limestone rocks. In the Argentina case study, the analysis reveals two HVSR peaks, with the first one associated with the sediment-basement interface and the high-frequency one linked to a shallower stratigraphic discontinuity. Temporal analysis of the high-frequency peak highlights cyclical patterns correlated with estuarine levels, suggesting a relationship between variations in seismic velocities and tidal dynamics. Comparisons with aquifer data support this interpretation. For the Maltese island, variations in amplitude spectra which can be related to the variation of the upper water table. This work has been supported by DEMUWA project which is financed by the Malta Council for Science and Technology through the Space Research Fund (Building Capacity in the Downstream Earth Observation Sector), a program supported by the European Space Agency. Funds were also made available through the IPAS (Internationalisation Partnership Awards Scheme), funded by the Malta Council for Science and Technology.
