	Objectives
	THE COURSE AIMS TO PROVIDE WORKING AND DESIGN PRINCIPLES OF MOST COMMONLY USED WATER WORKS IN BUILDINGS, WITH PARTICULAR ATTENTION TO THE HYDRAULIC APPLIANCES. THEORETICAL TOPICS ARE SUPPORTED AND SUPPLEMENTED BY CARRYING NUMERICAL EXERCISES AND BY DEVELOPING AFFORDABLE TECHNICAL-ECONOMIC SOLUTIONS TO BE PRESENTED IN TWO PROJECTS (ONE FOR SEMESTER).

	Prerequisites
	IN ORDER TO SUCCESSFULLY FULFILL PREDETERMINED GOALS, KNOWLEDGE OF MECHANICS OF CONTINUUM SYSTEMS IS REQUIRED.

CLASSROOM PROJECTS
PRELIMINARY DESIGN OF A FIRE-FIGHTING WATER SYSTEM OR PRELIMINARY DESIGN OF HYDRAULIC EQUIPMENT SYSTEMS IN BUILDINGS.
PRELIMINARY DESIGN OF A DRAIN SYSTEM FOR CONVEYING URBAN RUNOFF FROM BUILDINGS.

	Teaching Methods
	THE COURSE CONSISTS OF THEORETICAL LESSONS, CLASSROOM AND LABORATORY EXERCITATIONS. DURING THE ACTIVITIES IN THE LOCAL LABORATORY, STUDENTS, SPLIT IN GROUPS, WILL DEAL WITH THE PROJECT OF HYDRAULIC SYSTEMS AND EQUIPMENT’S. AS GUEST IN THE LOCAL HYDRAULIC LABORATORY, THE STUDENT CAN OBSERVE AS WELL FREE SURFACE FLOW PROBLEMS.

	Verification of learning
	THE ACHIEVEMENT OF THE LEARNING OUTCOMES IS CERTIFIED BY PASSING AN EXAM WITH EVALUATION IN THIRTIETHS. THE EXAM INCLUDES A WRITTEN TEST AND AN ORAL TEST THAT TAKE PLACE ON DIFFERENT DAYS SCHEDULED. THE WRITTEN TEST IS PRELIMINARY TO THE ORAL EXAMINATION. THE ORAL EXAM INCLUDES THE PRESENTATION OF A TECHNICAL PAPER PRODUCED BY THE STUDENT INDEPENDENTLY OR IN GROUPS ON A TOPIC INDICATED BY THE TEACHER. THE WRITTEN TEST CONSISTS OF SOLVING TWO COMPUTATIONAL PROBLEMS. THE TEST HAS A DURATION OF NO MORE THAN 120 MINUTES AND IS AIMED AT VERIFYING THE ABILITY TO CORRECTLY APPLY THE THEORETICAL KNOWLEDGE, THE ABILITY TO UNDERSTAND THE PROPOSED PROBLEMS AND THE ABILITY TO COMMUNICATE IN A WRITTEN MANNER. DURING THE TEST IT IS NOT ALLOWED TO CONSULT TEXTS OR TO USE A PC OR SMARTPHONE; A POCKET CALCULATOR IS ALLOWED. THE TEST TAKES PLACE BEFORE THE ORAL EXAM AND IS CONSIDERED TO HAVE BEEN PASSED WITH THE ACHIEVEMENT OF A PRE-ESTABLISHED MINIMUM SCORE. THE ORAL EXAM CONSISTS OF A DISCUSSION LASTING ABOUT 15 MINUTES AIMED AT ASCERTAINING THE LEVEL OF KNOWLEDGE AND UNDERSTANDING ACHIEVED BY THE STUDENT ON THE THEORETICAL AND METHODOLOGICAL CONTENTS INDICATED IN THE SYLLABUS. THE ORAL TEST WILL ALSO ALLOW THE STUDENT'S COMMUNICATION SKILLS TO BE VERIFIED WITH THE LANGUAGE AND AUTONOMOUS ORGANIZATION OF THE EXPOSITION. THE ORAL EXAM INCLUDES A DISCUSSION OF THE DURATION OF ABOUT 15 MINUTES OF A TECHNICAL WORK PRODUCED BY THE STUDENT INDEPENDENTLY OR IN A GROUP ON A CASE STUDY PROPOSED BY THE TEACHER AS A LABORATORY ACTIVITY. THE DISCUSSION WILL ILLUSTRATE THE PROBLEMS POSED BY THE ASSIGNED CASE, THE POSSIBLE PROJECT ALTERNATIVES, THE POSSIBLE REGULATORY CONTEXT, THE METHODOLOGICAL APPROACH ADOPTED, THE ANALYSIS OF THE RESULTS OBTAINED. THE DISCUSSION CAN USE SLIDES AND PROVIDE FOR THE REQUEST FOR THEORETICAL INSIGHTS AND DETAILED CLARIFICATIONS BY THE MEMBERS OF THE EXAMINATION COMMITTEE. THE EVALUATION OF THE ORAL TEST WILL BE CARRIED OUT ON THE BASIS OF THE FOLLOWING INDICATORS: COMPLETENESS, PRESENTATION, RELEVANCE. THE TEST AS A WHOLE MAKES IT POSSIBLE TO ASCERTAIN BOTH THE CAPACITY FOR KNOWLEDGE AND UNDERSTANDING, AND THE ABILITY TO APPLY THE SKILLS ACQUIRED, BOTH THE ABILITY TO EXHIBIT, AND THE ABILITY TO LEARN AND DEVELOP SOLUTIONS IN INDEPENDENT JUDGMENT. THE FINAL GRADE USUALLY COMES FROM THE AVERAGE OF THE TWO TESTS. THE MINIMUM GRADE FOR PASSING THE EXAM IS 18/30. THE HONORS CAN BE AWARDED TO STUDENTS WHO REACH THE MAXIMUM SCORE OF 30/30 AND DEMONSTRATE TO BE ABLE TO INDEPENDENTLY APPLY KNOWLEDGE AND SKILLS ACQUIRED EVEN IN CONTEXTS DIFFERENT FROM THOSE PROPOSED IN CLASS.
