Summary, in English

Population growth and climate change have accelerated groundwater depletion globally. Interferometric synthetic aperture radar (InSAR) is a fairly new satellite remote sensing technique based on SAR images that offers a high-accuracy monitoring system of land surface motion driven by groundwater level changes in time and space that can never be achieved with point-in-situ measurements. In productive aquifers, over-pumping of groundwater results in the compaction of fine-grained material, seen as subsidence on the ground that can be measured via the InSAR technique. This technique has been frequently used to evaluate the condition of aquifers, particularly in arid and semiarid areas, in the last decade. This chapter aims to provide an overview of the studies carried out on this issue and explores the application of InSAR to tease out the connection between land subsidence caused by groundwater depletion and measured heads in multilayer aquifer systems. It investigates existing InSAR studies examining the relationship between groundwater levels and ground deformation in various aquifer systems, focusing on the critical role of confined aquifers. The chapter also details the InSAR techniques employed, highlighting challenges and advancements in data processing and analysis. Two case studies, that is, Houston, Texas, and Mashhad, Iran, are presented to illustrate how InSAR data, combined with groundwater head measurements, can help characterize aquifer properties and inform sustainable groundwater management strategies. Finally, the importance of accurate aquifer characterization for effective subsidence modeling and mitigation is emphasized.
