November's Digital Discovery session focused on the use of digital technologies to revolutionize the monitoring and modelling of global surface water and SDG 6.6.1. The session was hosted by Stuart Crane, a UNEP freshwater expert together with Sílvia Leirião, a water resources engineer with DHI.
Stuart showcased the Freshwater Ecosystems Explorer – a digital transformation partnership by UNEP, Google Earth Engine and the EU JRC using earth observation data, cloud computing and machine learning. This platform acts as a “virtual time machine” that maps the location and temporal distribution of water surfaces at the global scale over the past 3.7 decades, and provides statistics on their extent and change to support better informed water-management decision-making.
Silvia introduced DHI’s Global Hydrological Model (GHM), a subscription-based data portal spanning almost the entire globe and major river basins. It can be used for planning river operations, as well as for analysing flood and drought indexes and the impacts of river discharges.
