Global Water Watch

We regret to inform you that Global Water Watch (GWW) has been made unavailable during November 2026 as we work towards establishing a sustainable framework for its continued development and maintenance.

GWW has played an important role in demonstrating how satellite data of surface water can be made available to a large group of people. However, due to current limitations in team stability and funding, the platform has become outdated.

We appreciate your understanding. For more information please contact Bjorn Backeberg (bjorn.backeberg@deltares.nl) or Jaap Schellekens (jaap.schellekens@deltares.nl)

The archive of surface area of all reservoirs has been made available at github and also stored on zenodo. The code of GWW is also freely available.
