Corso di studio
CIVIL ENGINEERING FOR MITIGATION OF RISK FROM NATURAL HAZARDS
Hydrogeological risk assessment and mitigation
Primo Semestre (24/09/2018 - 17/10/2018)
Scope of the course is to introduce the student to fundamental surface and subsurfaces data in order to develop and understanding engineering geological models for application to engineering works and to geohazards.
Knowledge of fluvial system morphology and their changes, understanding the natural pathways and rates of movement of water and sediment and the role of active and fossil landforms. Moreover, fluvial forms and processes are recognized as a key component of river system in the EU WFD for mitigating flood risk and geomorphic hazard and for a sustainable river management and restoration.
Programma e contenuti
Definition and importance of engineering geology. Geological factors and their relation with engineering problems. The most important fields of application of engineering geology to foundations, slopes, tunnels, dams and earth structures. Basic aspects of engineering geology including map construction and interpretation (e.g. engineering geological mapping units). Significance of ground profiles to engineering design, their origin in various geological settings. Engineering geological model types and terminology: conceptual and observational approaches. General rules for the construction of useful models. Use of surface and subsoil data in creating model of the ground, development of engineering geological models involved in civil engineering projects and in geohazards. Some examples of engineering geological models for geohazards assessment in different geological and geomorphological environments.
Fluvial system and their component; Geomorphic classification of rivers and streams; Factors controlling channel morphology; Fluvial processes; Channel types; Channel morphology variability and channel adjustment; Material and method to study fluvial geomorphology
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 earthquake and landslide hazard drawn from the experience of the instructor.
