Climate change is altering the water cycle and droughts are, and will be, increasingly recurrent. The resulting significant water stresses must be anticipated and limited to avoid water use restrictions during the summer season. Despite the expertise of the territory, the data currently available are generally incomplete, heterogeneous, scattered or obsolete.
“Monitoring of hydrological processes requires repeated observation in both space and time to detect the sources and modes of transport of water and material flows in watersheds. Since the hydrological process is by nature highly heterogeneous, the more repeated the observation, the more reliable and informative it will be. Carbonneau and Piégay (2012) observe that the need to study and measure watersheds holistically naturally leads to remote sensing as a basic tool. Indeed, spatial data are the only data that allow continuous measurement at the watershed scale.” (Source : Theia website https://www.theia-land.fr/ ).
Imagery and space technologies, combined with in-situ data, have a high level of utility in providing large-scale, consistent, up-to-date, and comprehensive information.
The MEOSS WaterManagement suite of services is constantly evolving. It offers various and complementary tools to observe, assess and anticipate water-related risks and stresses.
