OVERVIEW

Geo-hydrological hazards derives from Earth surface processes due to the interaction between meteo-hydrological phenomena and the geological environment, natural or human-modified, which can potentially lead to the loss of exposed elements at risk.

Among the most widespread and recurrent geo-hydrological hazards landslides and floods are presented.

AIMS AND CONTENT

LEARNING OUTCOMES

The goal of the course is to provide knowledge on the identification, monitoring techniques and management of geo-hydrological hazard, intended as the natural process related to the interaction between meteorological phenomena (even in the light of ‘climate change’) and the geological/geomorphological environment. In particular, floods and landslides are explained as widespread, recurring and hazardous phenomena. A part of the course provides knowledge to students on the geo-hydrological hazard processes: i) in the land-use planning; ii) to support the Environmental Impact Assessment and Strategic Environmental Assessment procedures; iii) in the forensic geology activities. Finally, the course provides knowledge on the main actions aimed to geo-hydrological hazard reduction and related risk.

AIMS AND LEARNING OUTCOMES

The attendance and participation in the training activities will allow the student to acquire the general knowledge of 'Geo-hydrological hazards'  as specific skills of the Geologist in order to interact with other pratictioners in the planning and management, identification of prevention measures for the geo-hydrological risk reduction. Specifically, the student will be able to:

• analyse significant meteo-hydrological events and evaluate any climate trends
• analyse geo-hydrological hazard processes in Master Plans and Urban planning tools
• recognize the effects on the ground after significant rainfall events and represent the geo-hydrological hazard through geo-thematic mapping
• identify the most appropriate techniques for monitoring the geo-hydrological hazards
• discuss the results of the monitoring of geo-hydrological phenomena and use them for risk reduction purposes
• critically evaluate the data collected during the survey activity, either directly on the territory or using existing cartography or remote sensing, to develop scientific and technical analyses
• preparing scientific and technical reports

PREREQUISITES

Basic knowledge of Geomorphology, Geomorphological Survey and mapping, Engineering Geology is considered mandatory to effectively address the contents of the teaching. 

TEACHING METHODS

For the first semester, the lessons will be carried out in presence if possible, guaranteeing the attendance of the lessons also at a distance, through video recording, synchronous or asynchronous. The laboratory exercises will be organized if possible in presence, also with sessions.

All activities in presence will be carried out in compliance with the capacity limits of the classrooms/laboratories and the distance between students, as provided by the regulations in force following the COVID19 emergency.

Teaching includes frontal lessons, workshops, on-site survey.

The teaching of Geo-Hydrological hazard is carried out with a practical approach to ensure the immediate comprehension of the subject in theoretical and applicative terms, using exercises, tests, research and studies.There will be teaching support activities by Geologists consultant, Geologists employed in the public administrations, Researchers belong to the National Research Council, Institute for Geo-hydrological Research and Protection.

The classroom lectures are delivered through multimedia presentations.

The workshop activities are aimed at the application of the theoretical knowledge acquired during the frontal lessons and field surveys. In particular, there will be laboratory exercises on applied hydro-geomorphology items proposed for the examination test for geologist pratictioner.

The on-site exercises are aimed at the recognition, monitoring and management of geo-hydrological hazards in regional and extra-regional catchments. There will also be exercises on buildings sites, urban areas and at local authorities (Land Planning and Management, Civil Protection).

Please refer to the AulaWeb instance specific of the teaching for any updates due to health and epidemiological situation changes.

SYLLABUS/CONTENT

The course program includes the presentation and discussion of the following tasks:

GEO-HYDROLOGICAL HAZARD

EXAMS

EXAM DESCRIPTION

The final test consists of a practical test and an oral test. The practical test consist  in the development of a project related to a geo-hydrological hazard case-study, similar to that of the qualifying examination to the Geologist pratictioner, with regard to idro-geomorphology issues.

The oral exam consists in the discussion of the practical test and in the verification of the learning of the subjects presentend during the teaching, as explained in the program course.

Please refer to the AulaWeb instance specific of the teaching for any updates due to health and epidemiological situation changes.

ASSESSMENT METHODS

The methods for the final test preparation and the levels of detail required will be provided during the lecturers.

The practical test will verify the ability to analyse, comprehend and manage the geo-hydrological hazards, including the risk reduction interventions and discussions.

The student should be able to link the knowledge gained during the classroom exercise activities with that provided during the frontal lessons by applying it to case studies developed during the on-site exercises and workshops.

The oral test concerns the discussion of the practical test and aims to evaluate the level of knowledge achieved, the ability to recall theoretical notions by applying them to real contexts. The ability to present the arguments and the use of correct scientific terminology are also assessed.

Lecturers attendance is strongly recommended
