This work examines the geomorphological features and geo-hydrological hazards of the Bisagno Stream catchment, focusing on anthropogenic interventions that have led to severe morphological changes. The study provides valuable information for land-use planning and management, particularly in mitigating geo-hydrological hazards.
This work presents the geomorphological features associated with the anthropic morphogenesis of the Bisagno Stream catchment, combined with the geo-hydrological hazards associated with landslides and floods. This catchment is internationally known for its recurring high-magnitude floods and its geo-hydrological hazards associated with the large and widespread presence of elements exposed at risks. It experienced severe morphological changes due to anthropogenic interventions related to urban sprawl and agriculture. Anthropogenic modifications to the former landscape have been particularly widespread and pervasive over the coastline, the floodplain, and the slopes. They include a general alteration of the pristine landforms, excavation and landfill forms, channelization and culvert of riverbeds, and terraced slopes. The 1:20,000 scale map allows to assess the relationships existing among structures and infrastructures, anthropogenic landforms, and landslides and flood-prone areas. Thus, this tool provides relevant information for land-use planning and land management, in particular under the perspective of geo-hydrological hazards mitigation.
