The course covers the analysis, design and management of pumping stations and hydropoweer plants. During the course, plants operating in water supply systems, in hydro power plants, in drainage systems will be analyzed.
Objectives: To provide the basis of dimensioning and design of the major hydraulic structures, also of large dimensions, and of infrastructures.
Topics: Fundamentals and procedures of design of the most important hydraulic structures (dams, dikes, channels, land reclamation, harbors, hydropower plants .). Hydraulic problems related to transport infrastructures (bridges, roads, .). Validation of the functional scheme and of the reference rules related to the structure design.
THe course material (slides and othe documents) will be provided during lectures.

The course covers the analysis, design and management of pumping stations and hydropoweer plants. During the course, plants operating in water supply systems, in hydro power plants, in drainage systems will be analyzed. The specific objectives will be the learning of the fundamental design and mangament principles for pumping station and hydropower plants
The course aims to provide the basis for dimensioning and design of the major hydraulic structures also of large dimensions, and of the infrastructures.
The functional scheme will be also defined and the reference rules related to the structure design will be discussed with reference to dimensioning and design of:
1) structures for territory and human activities protection from flood risk;
2) structures for water resources enhancement;
3) structures for the solution of the hydraulic problems related to transport infrastructures.
Fluid Mechanics, Hydrology and Hydraulic Structures, Structural Mechanics and Structural Engineering, Soil mechanics
The course includes lectures, exercises and
a Project work with the preliminary design of a pumping station and a mini hydro power plant
The course is developed in lectures and traditional classroom discussions, seminars and practical applications possibly on specific topics by experts, dedicated primarily to some topics.
Part of the learning process is also the review activity of the project work, which can be carried out collectively in the classroom during the course.
Lectures notes, further documents to study in depth, useful dataset, can become available during the lectures period on Moodle platform at UNIFI http://e-l.unifi.it/
During the first weeks of the course the enrollment to the platform is required to the students the intend to attend the course.
Type of Assessment
Methods of evaluation- Grading
Projects Work evaluation
The grade will be based on exams, project, and homework.
Type of Assessment
The evaluation of the student profit is performed on the basis of an oral examination where also a project work, defined in agreement with the teacher, carried out on the basis of the course contents, individually or in small groups, is presented and discussed.
In the assessment of learning process is included also the student's activity during the lectures period: a) in the frame of review activity of the project work, shared and collectively carried out; b) presentation and discussion of specific topics, suggested by the teacher or for the student interest, to study in depth on the basis of available literature.
