Learning outcomes
At the end of the course, the trained student will be able to define the role of groundwater flow systems inside the framework of the watershed water budget and to set up an exploitation scheme of the aquifers. In particular the trained student will be able to: - evaluate and choose specific tools and techniques to measure hydrodinamic parameters (conductivity, transmissivity, storage) of the aquifer in relation to site geological conceptual model; to plan a sustainable groundwater exploitation scheme; to learn and apply computer-based tools to analyze hydrogeological data; to apply hydrogeological prospecting tools in the field. Field activities will be conducted along with the teaching of "Stabilità dei Versanti" for a total of 2 CFU.

Assessment methods
The exam is based upon a practical and an oral trial.
Practical exam could be performed, according the choice of the student, according one of the following two options: a) write a report with analysis and interpretation of hydrogeological data collected on the field during the outdoor laboratory activity at the end of the course; b) practical exercise at the computer by interpretation of hydrogeological data provided by the teacher.
Practical exam is evaluated according the following grades of judgment: Optimal-Good-Fair-Poor-Bad. With a judgment of “bad” there is no the admission to the oral examination and the practical trial must be repeated; in all other cases there is the admission to the oral examination.
Oral examination, in front of the teacher, is evaluated with a vote expressed in fraction of 30. Depending on the judgment of the practical trial the higher votation achievable in the oral test is as follows: Optimal-30/30 cum laude; Good-30/30; Fair-27/30; Poor-25/30.
Teaching tools
