The course aims to provide the basis for dimensioning and design of the major hydraulic structures, eventually of large dimensions.
The scenarios and the functional schemes will be also defined and the reference rules related to the structures design will be discussed with reference to dimensioning and design of:
1) structures for protection from flood risk of territory and human activities with reference also to urban environment and cities of art;
2) structures for water resources enhancement;
3) structures for the solution of the hydraulic problems related to transport infrastructures.
Specific Learning objectives achieved by the student at the end of the course:
KNOWLEDGE AND UNDERSTANDING
1. Knowledge of the main tools for the definition of hydrological variables, of the drainage networks and of the river basins; of hydrological and hydraulic modeling. 2. Knowledge of the methods for the design of the main hydraulic structures for the hydraulic protection of the territory, water resource management, hydraulic problems of transports infrastructures. 3. Knowledge of the main international, European and Italian regulatory and guidance tools for hydraulic structures design.
APPLYING KNOWLEDGE AND UNDERSTANDING
1. Ability to estimate the reference hydrological quantities for the design; definition of the territorial and environmental context in which the hydraulic structure is located; definition of the reference regulatory context. 2. Ability to design hydraulic structures for the hydraulic protection of the territory, water resource management, hydraulic problems of transports infrastructures. 3. Ability to analyze the effects of the construction of the hydraulic structures, to define the monitoring activities of the structure and its functioning, to plan the ordinary and extraordinary maintenance activities of the designed structures.
1. Identify and define indicators and descriptors to critically evaluate data, design variable and results. 2. Identify possible and potential connections between the various aspects of a topic and/or problem.
1.Present and articulate in written and oral form an essay. 2. Expose clearly and in appropriate language the information learned in the course.
Fluid Mechanics, Hydrology and Hydraulic Structures, Structural Mechanics and Structural Engineering, Soil mechanics.
The course is developed in lectures and students-teacher collective discussions, seminars and practical applications possibly on specific topics by experts, primarily dedicated to some topics.
Part of the learning process is also the review activity of the project work, which can be carried out collectively during the course as well as the field trips specifically organized.
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
The assessment of the learning process of the student is performed on the basis of an ORAL EXAM. A substantial part (40%) is constituted by the presentation and discussion of the PROJECT WORK, a case study, defined in agreement with the teacher, carried out on the basis of the course contents, individually or in a group.
The spirit of the PROJECT WORK is to show the knowledge of the methods and/or topics discussed within the lectures of the course and to carry out a professional technical presentation, written and oral, of the work done.
The structure of the document is proposed by the student and agreed with the teacher. Indications on the contents and useful references for writing are given within the course and as written document of the course education material.
The assessment will consider the following aspects:
Presentation quality: correct use of language, clearness of the presentation (figures and tables, with captions included), organization of the report ...;
Technical quality: structure of the report, validity of the methods, correctness of data analysis, of the evaluations and of calculations ....
The ORAL EXAM covers the entire program/syllabus of the course and it consists of two parts.
The first part of the examination consists of a presentation of a written report using slides (in a limited number for a duration of about 10-15 minutes) and its subsequent discussion/defense.
The second part of the examination test consists of a series of questions on the program/syllabus of the course.
If the second part of the oral exam is not passed, the grade of the practical test of the project work (if sufficient) can be saved for any successive examination.
The examination aims to verify through the discussion of the report and the questions, the following: i) Knowledge and ability to understand the topics covered in the course program; ii) Ability to apply knowledge and understanding in developing the project work; iii) Autonomy of judgement in critically assessing the choices made in the report; iv) Communicative skills in presenting through slides the main contents of one's own work (context/state of the art, general and specific objectives, data and methods description, limits and possible developments).
In the assessment of the 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.
Introduction to hydraulic structures and interventions of river basins and streams regulation.
Definition of reference scenarios and design variables through the joint use of investigation tools and dedicated software of: a) Hydrological modeling of a watershed (e.g. software HEC-HMS Hydrologic Engineering Center - Hydrologic Modeling System) for modeling of rainfall – runoff processes and hydrographs estimation and peak disharges at the river cross section; b) Hydraulic modeling (e.g. software HEC RAS Hydrologic Engineering Center - River Analysis System) to perform one dimensional hydraulic calculations for a full network of natural and constructed channels; c) Hydrologic and hydraulic modeling of urban drainage systems with reference also to water quality (e.g. EPA-SWMM (Environmental Protection Agency - Storm Water Management Model)).
Definition of regulations reference scenarios at national, regional and local level, for the characterization of the environmental frame.
Characterization of natural and artificial hydrographic networks.
