The information layer Intervention of naturalistic engineering locates in the area each work of this type surveyed by the Mountain Basins Service of the Autonomous Province of Trento. Furthermore, data relating to the geometric characteristics of the work and the geomorphological context in which it is inserted are reported. The interventions of naturalistic engineering are part of the cadastre of hydraulic works, managed through the Information System of the Bacini Montani service (SIBaM). The cadastre registers the infrastructures built to mitigate flood hazards (hydraulic - forestry works) and the infrastructures built to interfere with watercourses for specific land use requirements (e.g. bridges, crossings, ...).
