Subject fundamentals
The course aims to introduce the student to the fluvial environment and its interactions with the hydrographic basin and the landscape with the aim to show the complexity of spatio-temporal evolution of river systems. In order to make decisional choices, environmentally compatible, the students will be provide a plethora of tools concerning river dynamics and interventions
Expected learning outcomes

Knowledge of the the river system as a vector of water and solid matter, substances.
Knowledge of transport processes and their effects on the river systems in terms of temporal-spatial evolution of the fluvial environment. Knowledge of interaction dynamics between the river and the landscape. Knowledge of the problems related to the environmental protection and the use of water resources.
Prerequisites / Assumed knowledge
Basic knowledge of Hydraulics, Hydrology and open channel flows

Assessment and grading criteria

1) 20 % of the final grade is based on the assessment of a report which will be prepared in groups. Each group will take a presentation of the work.
2) 40% comes from a written exam concerning the first part of the course (points 1-9)
3) 40% comes from a written exam concerning the second part of the course (points 10-15). During this part of the exam the student is allowed to consult textbooks or notes.

In addition, the student can also request a further oral exam.
