Syllabus
Course Objectives
The course aims to provide the fundamental knowledge to understand the factors that generate risk in coastal and river areas and the tools to design risk mitigation interventions. Moreover, it aims to provide the fundamental aspects of designing key hydraulic structures in both coastal and river areas. Therefore, the course develops the ability to integrate knowledge and manage the complexity of issues related to land hydraulic protection, as well as the design of major engineering structures in coastal and river environments.
The objective of the course is to enable the student to acquire: i) the ability to re-elaborate what has been studied and to apply the acquired knowledge in practice: this also, and above all, in fields other than those in which the knowledge learned is traditionally used (Knowledge, Understanding, Applied Knowledge); ii) the notions necessary to be able to independently deepen what has been learned, both independently and with originality, and through comparison with the teachers and with the other students, in order to use the basic knowledge as a starting "platform" that allows him to reach to further results characterized by an increasingly greater maturity and an increasingly broad autonomy of judgment (Autonomy of Judgment and Ability to Learn); iii) the ability to convey to one's interlocutors, in a clear and complete way, the knowledge acquired at the end of the training course developed within the course (Communication).
Course Prerequisites
Mathematical analysis, Physics
Teaching Methods
· Disciplinary classrooms
· Problem solving
· Project Based Learning
· The scientific method for STEM
Assessment Methods
The exam consists of an oral examination. It will involve an interview in which both the theoretical aspects developed during the course and the practical ones will be analysed, including through the analysis of a case study identified by the student.
During the oral discussion, the critical skills and methodological rigor achieved by the student will be evaluated, as well as the contributions of originality, with reference to the topics covered by the course.
The oral examination aims to verify the level of knowledge and understanding of the course contents and to evaluate independent judgement, learning ability and communication ability. The discussion of the case study chosen by the student has the aim of understanding the student's ability to re-elaborate what has been studied during the course and to apply the knowledge acquired in practice, in cases of interest different from those developed during the lessons.
The final grade will be awarded according to the following evaluation criteria:
30 cum laude: complete, in-depth, and critical knowledge of the topics, excellent command of language, complete and original interpretative skills, full ability to independently apply knowledge to solve the proposed problems;
28 - 30: complete and in-depth knowledge of the topics, excellent command of language, complete and effective interpretative skills, able to independently apply knowledge to solve the proposed problems;
24 - 27: knowledge of the topics with a good degree of mastery, good command of language, correct and confident interpretative skills, good ability to correctly apply most of the knowledge to solve the proposed problems;
20 - 23: adequate knowledge of the topics but limited mastery, satisfactory command of language, correct interpretative skills, more than adequate ability to independently apply knowledge to solve the proposed problems;
18 - 19: basic knowledge of the main topics, basic knowledge of technical language, sufficient interpretative skills, sufficient ability to apply the acquired basic knowledge;
Insufficient: does not possess an acceptable knowledge of the topics covered during the course.

(1.5 CFU)
Irrotational wave flow. Potential flow, continuity equation, Bernoulli's equation.
Differential equations of irrotational flow with a free-surface.
Introduction of wave mechanics. Stokes' first-order theory.
Three-dimensional waves propagating in an undisturbed field.
The concept of "sea state," an overview of sea state theory.
Fundamentals of sea state theory and some basic relations in the theory of the sea states.
The function HS(t). The omnidirectional probability of the significant height at a given location. The probability of the significant wave height for a given direction of wave advance.
The definition of "sea storm" Fundamentals of "equivalent triangular storm " and the return period of a sea storm with significant height greater than a given threshold: R(HS>h).
Introduction to the conventional design sea state for the design of port or coastal defence structures.
RUBBLE MOUND STRUCTURES FOR COASTAL DEFENSE
(1.5 credits)
Definition of "rubble mound structures for coastal defence," which are built along the coast to protect it from erosion and sea storms. Their function is to dissipate wave energy, reducing its impact on the shore, creating a barrier that preserves the beach and the infrastructure behind it.
Typologies and construction characteristics of these structures.
Stability and failure criteria.
Identification of the various construction elements and their sizing criteria.
Sizing criteria for a berm on the front face of a structure.
Estimation of run-up and overtopping flow rates according to the Eurotop Manual.
FLOOD CONTROL RESERVOIR FOR FLOW REGULATION. WATER DIVERSION AND DISPOSAL WORKS
(1 credit)
Flood control reservoir: construction typologies, planimetric and altimetric distribution based on the local configuration (location, type, capacity), ancillary structures, and discharge laws.
Flow regulation using reservoirs: reservoir balance equation, outlet flow regulation, complete regulation, regulation with overflows, and deficit regulation.
Flood channels: Artificial channels for diverting excess water away from critical areas.
EXPANSION TANK FOR FLOOD REGULATION. EMERGENCY MEASURES FOR FLOOD PROTECTION
(2 credits)
Choice of expansion tank type based on the characteristics of the location. Sizing criteria.
Estimate of the reservoir volume to reduce peak flow.
Verification of the reservoir's hydraulic performance based on the reservoir curve. Performance analysis of different reservoir types.
Emergency measures for flood defense
Information to be taken in anticipation of a flood: reservoir management, temporary interventions on levees during floods, bank protection, emergency flood channels, proposals and measures to facilitate flood defense and closure interventions, protection of buildings and structures from floods
Bank breaks and their closures: levee overtopping, emergency measures for flood defence and for the closure of flood closures, permanent measures
