DESIGNING HYDRAULIC WORKS
The aim of the course is to analyze the different types of interventions for the hydraulic arrangement of watercourses in the plains and mountain basins, describing their function and efficiency, both hydraulic and environmental. The characteristics and artifacts of the works are illustrated, the theoretical and practical elements necessary for their design, implementation and management are provided, making the student able to understand the intrinsic interactions between water, structures and territory and to draw up an executive project of such works.
Learning outcomes declined with respect to Dublin descriptors:
- Knowledge and understanding
At the end of the course the student will have integrated his knowledge on the hydraulic modeling of flood propagation phenomena in watercourses and in floodable areas, even in non-stationary motion conditions. The student will also be able to know and understand the complex and intrinsic interactions between water, structures and territory; to know the main operating schemes of hydraulic refurbishment interventions and the criteria for sizing the elements making up the works in the river bed, to acquire sensitivity with respect to design criteria that also include environmental issues.
- Ability to apply knowledge and understanding
The student will have acquired the ability to integrate knowledge within the complex and intrinsic interactions between water, structures and territory. He will be able to apply design methods and criteria for the main works of river water management. He will also be able to use mathematical models and hydraulic modeling software of the systems even in non-stationary motion conditions.
- Autonomy of judgment
The student will be able to present and compare the different calculation models used, identify and define the most suitable indicators and descriptors to evaluate data and results obtained; will finally have the ability to identify possible and potential connections between the various aspects of a topic and / or a problem.
- Communication skills
During the course the student will have to collaborate within a work group, defining objectives, activities, tools to be used in the executive planning of the river works. During the exam the student will have to present and discuss the design documents drawn up during the course, using the technical-scientific language correctly. These skills will enable him to illustrate the problems inherent in the hydraulic arrangement of watercourses also to a non-technical public such as political decision-makers and administrators.
- Learning ability
The student will be able to integrate the acquired knowledge on the functioning of the main hydraulic works in the river and on the sizing criteria of these works, through the consultation of texts, manuals and scientific publications also available on the teacher's website and through the use of web search tools and software.
It is necessary to have acquired the following knowledge provided by the course of "Hydraulic protection of the territory":
Mathematical models to simulate the propagation of floods in watercourses and in floodable areas.
Definition of hydrographic basin and its characterization: hypsographic curve, altitude and average height. Definition of the main parameters of the watercourses.
Linear models of transformation of outflows: IUH. Convolution integral. Time lag. S. Invaso linear curve. Nash with n tanks. Correction method. Variational approach for the calculation of the average of the maximum annual maximum flow rates. VAPI for the estimation of the annual maximum levels of the full flood.

The objective of the examination is to verify the level of achievement of the previously indicated educational objectives.
The exam takes place through an oral test in which the ability to connect and compare different aspects treated during the course will be evaluated. In particular, the exam consists of a preliminary discussion of the design documents as well as of the theoretical aspects and the calculation models treated during the course. The student must demonstrate full mastery of the tools used and know how to justify the solutions adopted. It must also demonstrate that it has understood the formal, theoretical and practical aspects contained in the design procedures taught.
