Water level

Water level obtained with satellite altimetry

altimetry processing currently is : active help on altimetry

Surface variation observed with optical and radar imagery.

Water level and surface variations are combined to estimate

the total volume variation

External data

In Situ measurments are available on Hydrolare website.
