ABSTRACT
The work describes the results of experiments conducted at the Hydraulic Laboratory of the University of Pisa. Tests were conducted for stepped channels, drops, smooth and block ramps by equipping two models. For the case of stepped channels different step types were used: smooth steel steps, artificial rough steps and smooth steps with the presence of end sills; different runs, with respectively 20, 14 and 9 steps, have been considered. Experiments refer to “nappe flow” and “skimming flow” configurations. The main purpose of the work is the comparison of the energy dissipation among the different hydraulic structures.
