Contents The course is organized in different units:
•Design of stable alluvial channels
•Bank protection
•Flood control alternatives
Reference texts •G. Benini, Sistemazioni idraulico forestali, Ed. UTET, 1992.

•Didactic material available in APE-LEARNING or UNISTUDIUM website
Educational objectives The course examines advanced modeling river erosion and flooding process directed to hydraulic infrastructures design, to water resources management and to floods control.

The main expected learning results will be:
•knowledge and understanding of the hydrological cycle and key hydrological processes, rigorous or simplified approaches in estimating river erosion and flooding process;
•skill to select and design proper technical solution to reduce erosion or flood impact on urbanized territories.
Prerequisites In order to deeply understand mathematical models involved in the program of the course and to reach the expected learning results the following elements are required:
•Hydraulics: elements of Hydrostatics, open channel flow and pressurized flow.
•Hydrology: main components of hydrological cycle (precipitation, runoff, infiltration)and basic hydrological modeling.
•Structural Mechanics and Strength of Materials: materials mechanical response, elements of structural analysis.
Teaching methods The course is organized as follows:
•lectures on all subjects of the course;
•exercises on all subjects of the course;
Other information Nothing
Learning verification modality The exam of the course consists of an oral discussion, lasting about 45 minutes, over the contents of the course program.

The oral discussion is directed to check out the knowledge level over the course contents , the acquired ability to apply the studied models and techniques and the ability to select the proper methodology by self-judgement. Furthermore, the oral exam has also the objective to evaluate communication skills and the usage of an appropriate language about the theoretical and practical subjects of the course.

The grade of the exam is certified with the local grade system, which is a number on a scale from 18 to 30.
Extended program The course deals mainly with river erosion and flood control alternatives. These elements are directed to the hydraulic infrastructures design, to flood control and to water resources management. The course is organized in different units as follows:
•Design of stable alluvial channels
•Bank protection
•Flood control alternatives

Contents Hydraulic risk problems concerning the different stretches (mountain, medium-valley and valley) of a natural water course and mitigation measures that can be implemented, in the unitary view of the hydrographic catchment. The course also includes the presentation of a distributed model for the estimation of the sediments production at the slope scale.

Learning verification modality Oral exam aimed to verify the student knowledge, his discussion capacity, his applicative capacity related to solve some problems of water resource management. The exam consists in a discussion of about 30-45 minutes on 3 questions at least. The questions are related to different topics of the program illustrated during the lectures of the two units (Irrigation systems and Rehabilitation hydraulics) composing the teaching.
