Course Objectives
KNOWLEDGE AND UNDERSTANDING
The course aims to provide the student with the knowledge necessary for the geotechnical design of controlled landfills and permeable reactive barriers. Will be deepened knowledge regarding: site-selection criteria and geometry of a landfill; methods of analysis of the stability of a landfill during excavation and after waste collection, slope stability and cover system stability, design methods of bottom liner and along the banks of a landfill, design methods of cover and anchoring systems, design methods of leachate and biogas collection and removal systems. The course provides the knowledge necessary to carry out the risk analysis on a contaminated site and the design of a permeable reactive barrier.
APPLYING KNOWLEDGE AND UNDERSTANDING
At the end of the course, students will be able to carry out the geotechnical design of a controlled landfill, to draw up a technical report of the same project, to carry out a specific site risk analysis on a contaminated site and to design a permeable reactive barrier. Students will be able to use the knowledge acquired in order to solve geotechnical problems of medium/high difficulty to cope with problems of environmental protection and defense of the territory. The skills acquired can be used in professional contexts and in research field.
The achievement of the aforementioned skills will be pursued through lectures, consultation of textbooks and / or specific scientific publications, carrying out design exercises, critical individual study of the topics covered during the course.
MAKING JUDGEMENTS
The student will be able to integrate their knowledge, even at an international level, on regulatory issues and on the design methods of the projects addressed during the course.
COMMUNICATION SKILLS
The student will be able to communicate in oral form the topics of the course program, to carry out the calculations and draw up technical reports of the design exercises addressed during the course.
LEARNING SKILLS
The student will be able to deepen with a high degree of autonomy the topics under study for professional and research purposes.
Course Prerequisites
Environmental geotechnics
Teaching Methods
Lectures, carrying out design exercises, critical individual study of the topics covered during the course.
Assessment Methods
The exam consists of an oral test. It consists of a first part where the design exercises, developed during the course, are discussed. They refer to the following topics: the choice of the site and of the geometry of the landfill; stability analysis in static and seismic conditions, the design of the bottom liner, side liner, cover and anchoring systems, and the design of a permeable reactive barrier. The second part of the exam is aimed at ascertaining knowledge on the other topics of the course not subject to design exercises. The oral exam also has the aim of assessing the autonomy of judgment, learning ability and communication skills. The outcome of the exam will result from an average of the marks assigned on each question posed to the student. Grading criteria will be the following:
30 cum laude: complete, in-depth and critical knowledge of the topics, excellent language skills, complete and original interpretative ability, full ability to independently apply the knowledge to solve the proposed problems;
28-30: complete and in-depth knowledge of the topics, excellent language properties, complete and effective interpretative skills, able to independently apply the knowledge to solve the proposed problems.
24-27: knowledge of the topics with a good degree of command, good language skills, correct and safe interpretative skills, good ability to correctly apply most of the knowledge to solve the proposed problems;
20 - 23: adequate knowledge of the topics but limited mastery of them, satisfactory language skills, correct interpretative ability, more than sufficient ability to independently apply the knowledge to solve the proposed problems;
18 - 19: basic knowledge of the main topics, basic knowledge of technical language, sufficient interpretative ability, sufficient ability to apply the basic knowledge acquired;
Insufficient: does not have an acceptable knowledge of the topics covered during the course.
