Course Objectives
The module "Idraulica Applicata" is the second module of "Idraulica" course.
In this module, will become familiar with open-channel flow, mainly dealing with man-made channel problems. Students will learn qualitative trends of Gradually Varied Flow profiles and will numerically compute those profiles as a function of the flow characteristics and boundary conditions.

Course Prerequisites
Mathematical Analysis: functions of one or more real variables, limits, derivatives, integrals. Physics: measurement of physical quantities and units of measure. Principles and fundamental equations of mechanics. Energy. The energy conservation principle. Mathematical physics: scalars and vectors. Fundamental elements of vector calculus. Geometry of the masses.
Teaching Methods
Lessons (hours per year in the classroom): 32
Exercises (hours per year in the classroom): 24
Exercises (hours per year in the classroom): 24
Assessment Methods
The learning assessment involves carrying out a written test in which 3 problems will be proposed. The evaluation will consider both the procedure and the correctness of the obtained results. The positive result, if accepted, will be used for the average with the grade of the "Fondamenti di Idraulica" module for the calculation of the final grade of the "Idraulica" course (arithmetic average of the two modules, rounded up).
Texts
Lectures’ slides (for PowerPoint lectures only), exercises and solutions will be available on the course page on the KIRO platform.
