20802071 - ADVANCED HYDRAULICS

Advanced Hydraulics is a course aimed at giving a deep knowledge on incompressible fluids motion and on their Mathematical modelling. The course is also aimed at developing the skills necessary to formulate and use basic numerical models for solving the most common mathematical models of applied Hydraulics: the method of characteristics and the finite difference method.

The course belongs to the master of Civil Engineering for the Protection from Natural Hazards, which is aimed at preparing a highly qualified Civil Engineer in the field of the protection of the territory and civil infrastructures from hydrogeological and seismic hazards.
In this framework, the course defines conceptual hydraulic models of increasing complexity, with particular reference to the most common ones: the 1D and 2D hydraulic model.

At the end of the course the student:
1) will own a deep knowledge of Fluid Mechanics;
2) will be able to formulate a model able to simulate a considered phenomenon, starting from the theories dealt during the course;
3) will be able to solve computationally the model using basic numerical methodologies;
4) will be able to interpret critically the results obtained from numerical models.

Type of delivery of the course

Frontal lessons and exercitations. Lessons are recorded (in italian) and uploaded on moodle.

Type of evaluation

If the students does the project by the due time, he can choose two project, a topic and the teacher put a final question within an oral test. Otherwise the student chooses one topic and other two are proposed by the teacher within an oral test.
