In large hydrological basin, water mass loading can produce significant crustal deformation. We compare the monthly vertical component of 18 GPS sites located in the Amazon basin, with the deflection models derived from GRACE observations in the one hand, and derived from HYDL, a global hydrological model, in the other hand. The GPS dataset includes the largest deflections by hydrological loading ever recorded at two stations located in the center of the basin. The main result of the study is that the GRACE solution produced by GRGS (Groupe de Recherche en Geodesie Spatiale, Toulouse, France) produces the best agreement with the GNSS series with a correlation coefficient up to 0.9 in the center of the basin although 70% at best of the RMS variation in the GPS series is accounted.
