Hydro-geotechnical modelling of Como subsidence

The urban area of Como (Italy), due to its subsoil structure and historical evolution, is particularly susceptible to subsidence. Moreover, this phenomenon exposes the lakefront areas to an increasing risk of flooding. Following a procedural scheme including dataset creation and management, 2D and 3D conceptual model and coupled hydrogeological and geotechnical numerical simulations, the most critical zones and scenarios have been analyzed, assessing natural and anthropic groundwater perturbations as the major cause in triggering subsidence phenomenon. The main purpose of this work is to establish an effective tool in supporting groundwater management, forecasting subsidence phenomena and planning mitigation works.
