The volume was published at the end of the MIARIA project – Adaptive Hydrogeological Monitoring in support of the Alpine Integrated Risk Plan. The partners who led and implemented the project were, for Italy: the Lombardy Region (Italian leader), the Province of Lecco, the Polytechnic of Milan (Polo di Lecco) and the Polytechnic Foundation of Milan; for Switzerland: SUPSI – Swiss Italian Professional University School (Swiss lead partner) and the University of Italian Switzerland (USI). MIARIA monitored the territories of the Province of Lecco in the Lombardy Region and of Val Canaria in the Canton of Ticino. In these areas, some areas, of particular importance from the point of view of hydrogeological risk and characterized by similar landslide mechanisms, have been the subject of specific analyzes and the site of innovative technological infrastructure for monitoring and alerting. During the project, technological systems were used for the distributed acquisition of territorial data and for their communication to second generation control rooms, aggregating the information data on a phenomenological basis. In particular, the specific distributed monitoring action implemented – based on Wireless Sensor Networks technology – provided data that could constitute a dynamic map of the risk associated with the specific intervention area. The monitoring system can thus allow the dynamic forecast of the risk in the vicinity of the emergency, thanks to the information received in real time.
