Hydrology from space is one of the rising remote sensing field of application, with huge issues - environmental, human, economic... - to take into account. Among the issues, there's also the question of explaining how to use those data (from current as well as future satellites) to people not so used to remote sensing, why, how they are made, etc. -- in one word, outreaching hydrology from space. Some portals exist, such as the THEIA portal for land applications through which a number of space data dedicated to land applications (including hydrology) are available (https://www.theia-land.fr/en ).
SWOT will be a cornerstone of hydrology from space, and will also be a completely new concept. Some pieces of explanations exists through the CNES space technology training courses (animations available on demand with a license), but more can be done -- and will be, with a major focus on hydrology, but not forgetting the ocean, and the complementarity with currents techniques, including nadir altimetry.
