Negro River Basin, based on the synergistic analysis using
multisatellite observations and hydrological models. For the
period 2003--2004, changes in water stored in the aquifer is
isolated from the total water storage measured by GRACE by
removing contributions of both the surface reservoir, derived
from satellite imagery and radar altimetry, and the root zone
reservoir simulated by WGHM and LaD hydrological models. The
groundwater anomalies show a realistic spatial pattern compared
with the hydrogeological map of the basin, and similar temporal
variations to local in situ groundwater observations and
altimetry-derived level height measurements. Results highlight
the potential of combining multiple satellite techniques with
hydrological modeling to estimate the evolution of groundwater
storage.
