Obiettivi dell'insegnamento

The course drives the student to design hydraulic works for flood risk  reduction,  merging the Italian traditional design experience with the recent outcomes in  hydrology and fluvial processes.

The design  of the hydraulic works is defined according to consideration: on  residual risk  analysis, environmental, sediment transport and vegetation impacts, maintenance needs.

Italian and European laws on the river basin management and reclamation. Hydrology recalls: river geomorphology, flood modelling via distributed and lumped models. Flood risk analysis: flood routing models and numerical methods for hydraulic risk analysis. Basin scale erosion. Solid transport in river stream, suspended and bottom sediment transport, regime and equilibrium theories, debris flow routing. Structural and non-structural flood defences. Design of: longitudinal and transversal defences, retention basin, diversive channel, soil bioengineering techniques. Interaction between river restoration works and river ecosystem.

Lecture Hours = 60, Design laboratories for 40 hours


Risultati di apprendimento attesi

The student will be able to analyse the river  processes and design the most appropriate hydraulic works providing its size and its level of reliability.

The student will  be able to understand the most important fluvial process that the hydraulic works have to correct and will be able to identify the most appropriate works improving the river design works and reducing their  environmental impacts.

The student will develop the konoweledge and comprehension of  the most important fluvial processes such as water profile and energy dissipation effects, Sediment transport in river reach, Effect of vegetation type on river stream.

The student will experience the capacity of identify the main problems and the most appropriate fluvial defences using structural and non structural approaches.

The student will acquire a capability of autonomous work in design river engineerings works.

Prerequisiti

There aren't official mandatory pre-requisities to apply for the final exam. Nevertheless for full  comprehnsion of the lessons it is recomended to have at least made the  exams of Hydrology with basic statistic and probabilistic model and the Hydraulic 1.


Modalità di valutazione

The exam is an oral exam  the student will answer on  the arguments disscussed during the lesson and the laboratory. Laboratory results made during the course will be discussed. The Laboratory results need to be edit in one  report, that have to be delivered before the exam date.

The exam will verify the student capability in discussing the main concepts of flood risk management and  the design criteria of river engineering works.

Evaluation of student is made also on the  of the student discussion on fluvial process and their interaction with the designed structure.

The laboratory report have to be delivered at least one working week before the exam.
