Özet
This paper presents the first results of the RESERVOIR project, financed by the PRIMA Foundation. The project aims to develop an innovative methodology for the hydrogeological characterization of large-scale aquifer systems using satellite-based Earth Observation (EO) techniques; to integrate advanced EO techniques into numerical groundwater flow and geomechanical models; to enhance the knowledge on the impacts of agricultural and tourist activities on water resources by quantifying land displacement; to engage water management authorities and provide models for optimal management of the aquifer systems. Four water- stressed Mediterranean areas (i.e. the coastal aquifer of Comacchio in Italy, the Alto Guadalentin basin in Spain, the Gediz River basin in Turkey and the Azraq basin in Jordan) are selected as pilot sites. In these sites, agriculture is traditionally the most important economic activity, but in some of them, it has been progressively replaced by urbanization and touristic activities, which also have a significant impact on groundwater resources. Stakeholders in each pilot site were engaged with the aim to discuss the knowledge gaps in relation to sustainable groundwater management. Engagement consisted of interviews with local authorities, farmers, and technicians and the fill in of questionnaires to investigate user requirements. Low-cost and non-invasive EO data (Advanced Differential SAR Interferometry A-DInSAR) are processed to obtain ground displacement maps of the pilot sites. This information will be used for aquifer characterization and modeling.
