Abstract
This study presents the initial results of the ORCHESTRA project and offers initial indications that the integration of advanced digital technologies with Nature-based Solutions has the potential to significantly enhance urban water management in South Tyrol, with a focus on two pilot catchments in Bolzano. The proposed framework involves the development of a digital twin, which is continuously fed by dense IoT sensor networks, recreating the hydraulic behaviour of the city in real time. In parallel, a model calibrated by a Genetic Algorithm analyse these data to forecast runoff peaks and recommend adaptive control actions. The preliminary findings emphasise the potential of this hybrid strategy as a scalable solution for sustainable urban water management and that an interdisciplinary, data-driven approach can foster the transition toward intelligent, resilient and sustainable cities.
