Sentinel-1 data is being used to monitor groundwater resources in Catalonia. This data allowed the Cartographic and Geological Institute of Catalonia (ICGC) and the Catalan Water Agency (ACA) to create a tool to detect subsidence caused by aquifer exploitation and effectively monitor and manage groundwater levels.
Such service is especially relevant in Catalonia which faces significant challenges related to water resources such as frequent droughts, climate change, high population density, touristic pressure, extensive agricultural activities, and illegal groundwater extraction. In this context, Sentinel data provides a comprehensive monitoring system that allows to improve water management practices. This is essential not only for maintaining the sustainability of water resources but also for ensuring the economic viability and social cohesion of many communities and industries across the region.
