Monitoring of Sea Level Variations Using GNSS Technology

Abstract

In recent years the study of climate change, as it relates to hazard mitigation in coastal regions, relies heavily on sea level variations. This chapter assesses the use of Global Navigation Satellite Systems (GNSSs) for remote sensing of sea surface variations and demonstrates the possibility of measuring absolute sea level variations brought on by tsunamis, significant storm surges, etc., which is crucial for mitigating coastal hazards. © 2025 selection and editorial matter, Dileep Kumar Gupta and Abhay Kumar Singh; individual chapters, the contributors.
