| Academic discipline | ICAR/02 |
| Type of study-unit | Obbligatorio (Required) |
| Language of instruction | Italian |
| Contents | The course is organized in different units as follows. •Hydraulics of flow in river channels •Physical properties of sediment •Scour criteria and scour related problems •Flow in curved river channels •Alluvial bed forms and flow resistance •Sediment movement in rivers •Design of stable alluvial channels •Bank protection •Flood control alternatives |
| Reference texts | •A. Armanini, Principi di Idraulica Fluviale, Editoriale BIOS, Cosenza, 1999. •V. Ferro, La Sistemazione dei Bacini Idrografici, McGraw-Hill, Milano, 2002. •G. Benini, Sistemazioni idraulico forestali, Ed. UTET, 1992. •Didactic material available in APE-LEARNING or UNISTUDIUM website |
| Educational objectives | The main expected learning results will be: •knowledge and understanding of flow resistance in the two components of grain roughness and form roughness to be introduced in the flow-resistance formulas to determine the normal depth in a channel at a given discharge; knowledge and understanding of the hydrological cycle and key hydrological processes, rigorous or simplified approaches in estimating river erosion and flooding process. The main competence (i.e., the ability to apply the acquired knowledge) will be the identification and evaluation of proper approach for a wide range of problems in river engineering, i.e. in estimating sediment transport and bed load formulas to design hydraulic infrastructures 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; •seminars. |

| Learning verification modality | The exam of the course consists of two oral discussions (Exam Mode 1) or one oral discussion (Exam Mode 2) over the contents of the two parts of the course program. Exam Mode 1 The oral exams, each one lasting 45 minutes, to be performed separately or in the same exam session, are directed to check out the knowledge level over the course contents related to River Engineering and Flood Control Alternatives , the ability to apply the studied models and techniques and the ability to select the proper methodology by self-judgement. Furthermore, the oral exams have 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. The exam mark will be provided by a weighted average of the results obtained in the separate tests. Exam Mode 2 The oral exam, lasting 1 hour, is directed to check out the knowledge level over the course contents related to River Engineering and Flood Control Alternatives, the 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. |
