  abstract = {{I}n this study, we estimate monthly variations of surface-water storage ({SWS}) and subsurface water storage ({SSWS}, including groundwater and soil moisture) within the {L}ower {M}ekong {B}asin located in {V}ietnam and {C}ambodia during the 2003-2009 period. {T}he approach is based on the combination of multisatellite observations using surface-water extent from {MODIS} atmospherically corrected land-surface imagery, and water-level variations from 45 virtual stations ({VS}) derived from {ENVISAT} altimetry measurements. {S}urface-water extent ranges from 6500 to 40,000 km2 during low and high water stages, respectively. {A}cross the study area, seasonal variations of water stages range from 8 m in the upstream parts to 1 m in the downstream regions. {A}nnual variation of {SWS} is 40 km3 for the 2003-2009 period that contributes to 40-45% of total water-storage ({TWS}) variations derived from {G}ravity {R}ecovery {A}nd {C}limate {E}xperiment ({GRACE}) data. {B}y removing the variations of {SWS} from {GRACE}-derived {TWS}, we can isolate the monthly variations of {SSWS}, and estimate its mean annual variations of 50 km3 (55-60% of the {TWS}). {T}his study highlights the ability to combine multisatellite observations to monitor land-water storage and the variations of its different components at regional scale. {T}he results of this study represent important information to improve the overall quality of regional hydrological models and to assess the impacts of human activities on the hydrological cycles.},
