The NAIADES project envisions the use of digital innovations for improved water management in three pilots in Europe, Alicante (Spain), Braila (Romania) and Carouge (Switzerland). An important step in the project is the identification of needs and the subsequent definition of use cases. This task, carried out by IHE in collaboration with all the partners in the project, promoted discussions among partners and stakeholders during the first half of the project, which complemented the findings of earlier visits made to the pilots of Alicante and Braila.
