Welcome to the "hydro geodesy lab", the home of Susanna Werth at ASU!

Research at the lab focusses on enhancing techniques for monitoring water resources with gravity and deformation data. Geodetic remote sensing techniques that measure Earth's gravity changes and surface deformation are applied to obtain and analyze large-scale estimates of temporal changes in continental water mass budgets. Also, the impact of changes in water availability on environment, human societies as well as crisis management are approached.

This website provides inside into ongoing research and education programs at the lab.
