Course Objectives
The course provides the tools to understand the factors that generate flooding risk in coastal, river and urban areas and the tools to size risk mitigation interventions.
Therefore, the course develops the ability to integrate knowledge and manage the complexity of the problems related to the hydraulic protection of the territory and develops the communication skills necessary to communicate, in a clear way, the knowledge in the sector of the hydraulic protection sector of the territory. Furthermore, it hones the learning skills necessary to deepen the subject independently and in research contexts. The first part of the course describes the action of the waves on the coasts to evaluate run-up, set-up and coastal sediment transport.
Furthermore, the main coastal defence interventions are described (barriers, groins, nourishment) and the related effects on the adjacent coasts.
In the second part of the course the concept of risk in coastal, river and urban areas is defined, with the related regulatory framework, and the main assessment and mapping methodologies are described.
In addition, the interactions between the river current and the bridges, and between the hydrographic basins and the coastlines are described, analysing the conditions that favour the contemporaneity between floods and storm surges.
Finally, the last part of the course is dedicated to the description of the functionality of the main open source and free software for risk assessment in the urban and river environment (QGIS, HEC-HMS, HEC-RAS).
Course Prerequisites
Basics of Maritime construction, Coastal Engineering and Hydrology
Teaching Methods
Lectures (hours/year in lecture theatre): 36
Practical class (hours/year in lecture theatre): 12
Assessment Methods
Oral examination
Project Evaluation
The examination comprises an oral test. This test consists of an interview in which the exercises on the practical topics of the course will also be evaluated and discussed.
The oral test is intended to verify the level of knowledge and understanding of the course content and to assess the student's autonomy of judgement, learning ability and communication skills.
The outcome of the examination will depend on a weighted average of the results of the oral tests and the evaluation of the exercises. 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 language skills, complete and original interpretative ability, full ability to apply knowledge independently to solve the proposed problems;
28 - 30: complete and thorough knowledge of the topics, excellent language skills, complete and effective interpretative ability, able to autonomously apply knowledge to solve the proposed problems;
24 - 27: knowledge of the topics with a good degree of mastery, good language property, correct and safe interpretative ability, good ability to correctly apply most of knowledge to solve the proposed problems;
20 - 23: adequate knowledge of the topics but limited mastery of them, satisfactory language skills, correct interpretative ability, more than sufficient ability to apply knowledge independently to solve the proposed problems
18 - 19: basic knowledge of the main topics, basic knowledge of technical language, sufficient interpretative ability, sufficient ability to apply the basic knowledge acquired;
Insufficient: does not have an acceptable knowledge of the topics covered during the course.
