Screens may be utilized efficiently for dissipating the energy of water. In this
study, water flowing beneath a gate is used to simulate the flow downstream of a
hydraulic structure and screens are used as an alternative mean for energy
dissipation. Investigations are done conducting a series of experiments. The porosity,
thickness, and the location of the screens are the major parameters together with the
Froude number of the upstream flow. The scope of this thesis covers the situation
where there is a pseudo-jump formation. The experiments covered a range of Froude
numbers between 5 and 18, porosities between 20% and 60%, and location of the
screen up to 100 times of the undisturbed upstream flow depth. The thicknesses of
the screens used are in the order of the undisturbed upstream flow depth. The results
show the importance of each parameter on the energy dissipating performance of the
screens and the system. It is observed that screens dissipate more energy than a jump
within the range covered in these studies.
