The overall goal of the project is to achieve an improved characterization of the variations of water storage (and flow) and of the gravity field in large river basins world-wide by combining hydrological modelling and regional geodetic estimation using GRACE data. There are two equally important individual goals:

• to improve regional gravity field features using hydrological information derived from hydrological models, in particular the hydrological model WGHM;

• to improve global-scale hydrological modeling of water storage variations (and flows) in the different storage compartments (snow, soil, groundwater, surface water including floodplains) using information on the variation of the gravity field from GRACE.
