Interview with Arjen Haag, Researcher and Consultant in hydrology and water management at Deltares

Arjen Haag is a hydrologist and remote sensing analyst working at the Operational Water Management & Early Warning department of Deltares. We talk to him about the role that earth observation plays in his projects, SERVIR-Mekong, his experiences in the space and water sector and his vision for innovation in the remote sensing community. We ask him about challenges related to flood mapping and forecasting, whether water data should be shared openly and the transfer of knowledge to those needing it the most. He shares his insights on the use of satellite data, algorithms and models, as well as artificial intelligence and machine learning. And finally, why sandcastles were important for all of this.
