Contribution of the course to the overall degree programme goals
Specific objectives of the teaching are: to give know-how and operational capacity in studies connected with earth surface processes (morphogenesis vs pedogenesis), with emphasis on Quaternary deposits.
Expected learning outcomes
The student will have acquired the knowledge and the ability to analyze the cause/effect relationships between morphodynamic processes, morphostructures and morphoscultures.
Furthermore, the knowledge and ability to detect the effects of human interventions on the territory.
Ability to use and interpret aerial photographs of the territory to perform morphographic and morphometric analyzes, thanks to a limited knowledge of GIS software for the interpretation of digital photographs.
Furthermore, the student will have adequate knowledge and understanding of the geomorphological processes; this in relation to the spatial scales of the analyzed places as well as to the geological and climatic characteristics that characterize them. At the end of the course, the student is able to recognize morphogenic processes and related diagnostic forms.

Assessment methods
The test in the laboratory it is made of a geomorphological interpretation of the land through the analysis of aerial photographs. The interpretation of aerial photographs will take place by GIS. Through this tool will also be produced geomorphological maps that highlight the morphogenetic processes and related diagnostic forms. The weight of the grade will be 30% of the total.
The two grades will be integrated.
Teaching methods
Field trip with observations of forms and processes of several environments.
The laboratory sessions include the following topics:
- Chemical analysis of soils.
- Introduction to the use of GIS software; interpretation of aerial photographs by GIS; construction of geomorphological maps.
