Abstract:
GRACE satellite can be used to derive monthly regional groundwater storage changes, and the data can be freely downloaded, which provides a new method for regional groundwater management. The processes in the management of regional groundwater, the application of GRACE-derived groundwater storage and the current status of GRACE satellite used in regional groundwater management were summarized. GRACE-derived data can be successfully used to the assessment of regional groundwater storage by case studies from the researchers all over the world. GRACE-derived data can be used in model calibration for regional groundwater flow model. GRACE satellite shows great potential in regional groundwater management. However, there are two problems in the application of GRACE-derived data. One is that the date can not be directly used to evaluate regional groundwater resource. The another one is low spatial resolution of GRACE data. Studying on the method for effectively evaluating regional groundwater resources from GRACE satellite and improving the spatial resolution of GRACE-derived data are the problems to be addressed in the future.
