@article{fdi:010083350, title = {{S}urface water storage in rivers and wetlands derived from satellite observations : a review of current advances and future opportunities for hydrological sciences}, author = {{P}apa, {F}abrice and {F}rappart, {F}.}, editor = {}, language = {{ENG}}, abstract = {{S}urface water storage ({SWS}), the amount of freshwater stored in rivers/wetlands/floodplains/lakes, and its variations are key components of the water cycle and land surface hydrology, with strong feedback and linkages with climate variability. {T}hey are also very important for water resources management. {H}owever, it is still very challenging to measure and to obtain accurate estimates of {SWS} variations for large river basins at adequate time/space sampling. {S}atellite observations offer great opportunities to measure {SWS} changes, and several methods have been developed combining multisource observations for different environments worldwide. {W}ith the upcoming launch in 2022 of the {S}urface {W}ater and {O}cean {T}opography ({SWOT}) satellite mission, which will provide, for the first time, direct estimates of {SWS} variations with an unprecedented spatial resolution (~100 m), it is timely to summarize the recent advances in the estimates of {SWS} from satellite observations and how they contribute to a better understanding of large-scale hydrological processes. {H}ere, we review the scientific literature and present major results regarding the dynamic of surface freshwater in large rivers, floodplains, and wetlands. {W}e show how recent efforts have helped to characterize the variations in {SWS} change across large river basins, including during extreme climatic events, leading to an overall better understanding of the continental water cycle. {I}n the context of {SWOT} and forthcoming {SWS} estimates at the global scale, we further discuss new opportunities for hydrological and multidisciplinary sciences. {W}e recommend that, in the near future, {SWS} should be considered as an essential water variable to ensure its long-term monitoring.
