Learning outcomes Objectives:
Being a specialized curricular unit of Civil engineering, it's intended to provide the students with knowledge in the fields of soil erosion in river basins, the hydraulics of flow with mobile beds, the design of fluvial regulation and flood control structures and the prediction of bed erosion and the application of countermeasures.
a) Knowledge on the characteristics of flows over mobile beds (transport of sediments and bed forms).
b) Ability of the design of fluvial regulation and flood control structures.
c) Ability of the prediction of bed erosion and the application of erosion countermeasures.
d) Knowledge on the fundamental concepts of Fluvial Hydraulics (open channel flows and soil erosion).
Syllabus 1. THEORETICAL BACKGROUNG: Hydraulics complements; Dimensional analysis; Physical properties of sediments; Soil erosion and sediments production.
2. FLOWS OVER MOBILE BEDS: Beginning of bed-load transport; Bed forms; Fluvial morphology; Resistance to flow; Transport of sediments; Stable channels.
3. FLUVIAL REGULATION AND FLOOD CONTROL STRUCTURES: ex. regulation of the main channel; riprap revetments; groynes; dykes; flood control with detention basin; use of vegetation.
4. EROSION PREDICTION: Generalized bed erosion; Local scour; Countermeasures.

Teaching Methodologies and Assessment Criteria This one-semester Course Unit involves 60 hours of scheduled contact activities organized in theoretical classes (45 T: presentation of syllabus and learning of methods and techniques in the context of fluvial design works) and practical classes (15 PL: where students, working in groups, perform the practical work, and may include a technical visit). The drawing up of the reports is part of the autonomous work. The application of knowledge will be ensured through the use of numerical modeling software of different river flow scenarios in a river section.

The evaluation is carried out in two phases:
- Continuous assessment: includes two tests (theoretical and practical) and practical work carried out in class, with the submission of reports.
- Final exam: includes one exam (theoretical and practical) and practical work carried out in class, with the submission of reports, for admitted students.
Language Portuguese. Tutorial support is available in English.
