| THE COURSE OF HYDRAULICS IS AIMED TO PROVIDE ENGINEERING STUDENTS WITH THE CONCEPTUAL AND THE PRACTICAL TOOLS FOR SOLVING MANY PRACTICAL PROBLEMS OF INTEREST TO CIVIL ENGINEERING KNOWLEDGE AND UNDERSTANDING: A) FROM A GENERAL POINT OF VIEW OF THE COURSE IS AIMED TO PROVIDE THE KNOWLEDGE AND THE UNDERSTANDING OF THE BASIC PRINCIPLES OF HYDRAULICS IN THE FIELD OF CIVIL ENGINEERING ACQUIRED THROUGH THE STUDY OF TEXTBOOKS. B) FROM A SPECIFIC POINT OF VIEW THE COURSE IS AIMED TO PROVIDE THE KNOWLEDGE NECESSARY FOR THE UNDERSTANDING OF THE: - PRINCIPLES THAT GOVERN THE PRESSURE BEHAVIOUR IN FLUIDS AT REST AND IN MOTION - LAWS THAT GOVERN THE MOTION OF FLUIDS FOR BOTH PRESSURE AND FREE-SURFACE FLOWS - CONCEPTS RELATED TO THE MOTION OF GROUNDWATER ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING: A) FROM A GENERAL POINT OF VIEW THE COURSE IS AIMED TO PROVIDE THE ABILITY TO APPLY KNOWLEDGE AND UNDERSTANDING TO ADDRESS SCIENTIFIC AND PROFESSIONAL ISSUES RELATED TO BASIC HYDRAULICS IN CIVIL ENGINEERING B) FROM A SPECIFIC POINT OF VIEW THE COURSE IS AIMED TO PROVIDE THE KNOWLEDGE NECESSARY TO: - CALCULATE FORCES ACTING ON PLANE AND CURVED SURFACES; - CHECK AND SIZING PIPES UNDER PRESSURE; - DETERMINE BACKWATER PROFILES CYLINDRICAL CHANNEL JUDGEMENT: ABILITY TO GATHER AND ANALYZE DATA IN ORDER TO MAKE JUDGMENTS AND SELF-ASSESSMENTS NOT ONLY OF TECHNICAL NATURE, BUT ALSO ON SOCIAL AND ETHICAL ISSUES RELATED TO HYDRAULICS PROBLEMS IN THE FIELD OF CIVIL ENGINEERING COMMUNICATION SKILLS: COMMUNICATE COMPETENTLY INFORMATION, IDEAS, PROBLEMS AND SOLUTIONS RELATING TO HYDRAULICS PROBLEMS IN THE FIELD OF CIVIL ENGINEERING TO TECHNICAL PARTNERS AND TO TRANSFER BASIC CONCEPTS ANDS SOLUTIONS TO NON-TECHNICAL STAKEHOLDERS LEARNING SKILLS: ACQUISITION OF THEORETICAL AND PRACTICAL TOOLS NEEDED TO SOLVE NEW HYDRAULICS PROBLEMS IN THE FIELD OF CIVIL ENGINEERING AND / OR TO PURSUE HIGHER STUDIES IN THE FIELD OF ADVANCED HYDRAULICS THE COURSE INCLUDES, IN ADDITION TO THE RIGOROUS TREATMENT OF THEORETICAL ASPECTS, THE PERFORMANCE OF SEVERAL NUMERICAL APPLICATIONS IN CLASSROOM AND PRACTICAL EXERCISES IN THE LABORATORY. THE COURSE CONSISTS OF 120 H, OF WHICH ABOUT 60% IS DEVOTED TO THEORY, 30% IS DEVOTED TO APPLICATION AND 10% TO EXAM PREPARATION. NO PROJECT WILL BE DEVELOPED IN THIS COURSE. |
