In a joint effort DRIVER partners successfully inaugurated the platform in The Hague by conducting a large-scale experiment involving an overall number of approximately 150 volunteers (135 citizens and 15 CM professionals), 26 technicians and experiment organizers, 28 external observers, 9 evaluators and 7 DRIVER solutions. The experiment took place at the VRH premises over two days on April 19th to 20th and assumed a flood scenario in which a combined high tide with an extreme weather event threatened the citizens in the region of The Hague.
