HYDRAULICS OF NATURAL SYSTEMS

Students will gain knowledge of advanced mathematical tools and of lab and field experimental results for studying the motion of fluids in the different contexts in which they exist in nature. The focus is, in particular, on fluvial hydraulics, on debris flows and on maritime hydraulics, both in fixed and movable bed conditions.

Class lessons are held; for each topic, problems relating to practical engineering applications are solved by the students, under the guide and with the assistance of the teacher.

A list of main topics follows.

The river system. Uniform, steady and unsteady open channel flow. Incipient motion and sediment transport. Resistance to flow in movable-bed channels. Water-sediment interaction: fluvial morphodynamics. Debris and mud flow. Principles of oceanography. Regular waves and their transformations. Irregular waves. Short-term and long-term statistical analysis. Wave design parameters. Surf zone hydrodynamics. Coastal processes.
