Research group NG| Hydrogeodesy Lab
By using geodetic methods to measure or infer hydrological quantities and their changes over time, Hydrogeodesy supports hydrological monitoring, management, and research via measurements that standard hydrological observations cannot obtain.
While most hydrological observations are point measurements of hydrological variables, such as water level or soil moisture, hydrogeodetic observations are obtained indirectly from geodetic data. These data are then translated to hydrological quantities, such as terrestrial water storage, snow depth, and surface water level. Hydrogeodetic studies that address hydrological problems beyond technical developments, such as those aiming to understand hydrological and geomorphological processes or human impacts are scarce. Hence, we use optical and SAR observations, interferometric SAR (InSAR), and altimetric data, in combination with hydroclimatic frameworks and artificial intelligence, to understand these processes and address key sustainability and water-related science challenges.
Group description
Hydrogeodesy is the discipline that uses satellite-based geodetic observations to understand changes in water availability, distribution, and movement (Jaramillo et al., 2024). We aim to go beyond the typical technical uses of hydrogeodetic techniques to address the goals of key hydrological and sustainability science frameworks and water management.
