CIVIL ENGINEERING FOR MITIGATION OF RISK FROM NATURAL HAZARDS
Hydrogeological risk assessment and mitigation
Secondo Semestre (08/03/2021 - 30/03/2021)
58 ore di attività frontale
Basic knowledge of engineering geology.
Scope of the course is to introduce the student to recognize and characterize different types of slope instabilities and to be able to use tools for the landslide hazard and risk assessment, to select techniques for monitoring and mitigation of landslide risk.
Programma e contenuti
Landslide terminologies and types, classifications. Landslide dynamics. Predisposing and triggering factors, landslide occurrence as a consequence of land use and climate changes. Methodologies of landslide investigation and mapping, landslide inventories. Methods for landslide susceptibility and hazard assessment (initiation and run out): knowledge –driven, data-driven and physically based methods. Evaluation of the performance of landslide zonation map. Landslide monitoring and early warning: ground-based and remote surface displacements measurement techniques, monitoring of hydro-meteorological variables. Rainfall threshold for landslide prediction. Landslide mitigation: structural and non-structural protection. Lesson learnt from some case histories.
Landslide Risk analysis, assessment and management: from Qualitative to Quantitative Risk Analysis , human induced landslides and the role of human activities in relation to landslides, landslide risk assessment and sustainable development: methods and tools for land-planning, risk management framework, resilience assessment, case histories.
The course is integrated and complemented by computer lab exercises concerning landslide hazard and risk assessment and field trip to landslides in the Alps and in the Apennines.
The course consists of lectures to illustrate the theory and tutorial sessions where the emphasis is on applications and problem solving. Each subject is illustrated with the support of experimental and observational evidences and well-documented case histories concerning landslide hazard and risks drawn from the experience of the instructors.
