The course provides basic knowledge of geology and geomorphology necessary for the various typical activities of civil and environmental engineering.
The course is aimed at students with a basic background and is aimed at providing knowledge regarding the nature and formation of rocks, geomorphological and geodynamic processes, notions of tectonics and stratimetry. This knowledge represents a necessary background for the subsequent courses in Geotechnics, Hydraulics and Materials Science
Geology is the primary Earth Science and looks at how the Earth formed its structure and composition, as well as the types of processes acting upon it.
This course provides fundamental geological knowledge, particularly regarding the lithosphere, the phenomena that occur within it, and their relationship with human activities. This knowledge forms a necessary foundation for subsequent courses in Environmental Engineering, Geotechnics, and the Science and Technology of Materials.
The course combines theoretical and practical studies and aims to enable students to acquire skills relevant to different areas of Civil and Environmental Engineering, thus allowing them to characterise the different geological contexts in which a civil and environmental engineer will have to work.
Students will be able to know the main mineral-petrographic characteristics of the most common rocks, the morphologies and the morphological evolution of the land, the tectonic structures, to have general knowledge on geodynamics, to draw simple geological sections and to interpret a geological map.
At the end of the course, students will have acquired knowledge about:
- Fundamental principles of the Earth Science: geological timescales, principles of stratigraphy, Earth’s internal and external structure features
- Main mineralogical and petrographic characteristics of rocks, tectonic structures, landscape morphologies and sedimentary deposits
- Guidelines for geological maps analysis
- Guidelines and methodologies for geological cross-sections construction and analysis
At the end of the course, students will have acquired abilities for:
- Identifying minerals and classifying rocks
- Drawing geological cross-sections and interpreting geological and hydrogeological maps at different scales
- Using technical language for the description of geological structures and the analysis of geological settings
General knowledge of physics and chemistry are required
Basic knowledge of mathematics, physics, chemistry and geography.

Exercises (2 credits):
Macroscopic recognition of rock samples;
Drawing of hydrographic basins;
Realization of geological sections
The course is subdivided into three main sections.
Section I:
The Earth system: the geochemical composition of the crust and the subdivision of the Earth on a geophysical basis (Preliminary Reference Earth Model). The general classification of minerals and rocks: igneous (intrusive and effusive), sedimentary, and metamorphic rocks. The cycle of rocks. Structure, texture, and attitude of the rocks. Weathering of the rocks (2 credits)
Section II:
Principles of sedimentary geology. Sedimentary environments, landscape morphologies, and deposits: Alluvial plains and alluvial fans, meanders, deltas, and coastal areas (1 credit)
Section III:
Principles of structural geology (folds, faults), geodynamics (plate tectonics, volcanism, seismicity)
Elements of geological mapping: attitude of geological layers and their relationships with the topography (topographic map)
Principles of hydrogeology: underground water circulation, the geology of the aquifers aquifer and hydrogeological basins
Landslides and geological in-situ tests (direct and indirect methods) (1.8 credits)
Exercises (1.2 credits):
Macroscopic recognition of rock samples
Interpretation of geological maps at different scales and construction of geological sections (traditional methods and/or use of available open-source software)
The course is 60 hours long and it is organised as follows:
40 hours are dedicated to lectures on basic theoretical aspects
The 20 hours of practice will be divided as follows:
5 hours of macroscopic recognition of samples of common rocks (igneous, sedimentary and metamorphic)
3 hours tracing of a catchment area
12 hours realization of geological sections
Technical visits are planned for the in situ observation of rocks and morphologies
Lessons and exercises will be held in plenary sessions.
The course is organised as follows: 42 h dedicated to lectures on basic theoretical aspects and 18 h dedicated to practical exercises.
Technical visits are planned for the in situ observation of rocks, sediments and landscape morphologies.

The exam is aimed at evaluating knowledge, competences and skills acquired during the course.
One question for each part of the course (0 to 9 points for each question)
Evaluation of the exercises carried out during the course (from 0 to 3 points)
Rules during oral exams:
the student will need a paper sheet and a pen
the student must show his/her identification document
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Written test; Optional oral exam;
Written test; Optional oral exam.
The exam is aimed at evaluating theoretical knowledge and practical abilities acquired during the course. In detail, the written exam is meant for verifing the above reported skills (see Expected Learning Outcomes): identifying minerals and classifying rocks, drawing geological cross-sections and interpreting geological maps at different scales, using technical language for the description of geological phenomena, structures and the analysis of the specific cartography.
The written examination lasts 1 hour and consists of a set of closed (15) and open (4) questions, numerically evaluated. In the open questions, the notational clarity and the exhibition rigor allow acquiring the laude. During the examination, it is not allowed to hold and consult notebooks, books, sheets with exercises, forms, calculators.
The results of the written exam are communicated on the teaching portal, together with the date on which students who pass the written exam (>18/30) can ask to take the optional oral exam.
The oral exam (2-3 questions) is designed to assess the main concepts learned and may confirm or adjust the grade from the written test (increasing or decreasing it by up to 3 points). It covers the entire course content and lasts between 15 and 20 minutes. Additionally, the oral exam may be conducted at the discretion of the instructor if further clarification is needed after the written test.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
