The main goal of the present study is to investigate the energy dissipation
through inclined screens. Recent studies have shown that screens arranged vertically
may dissipate more energy than a hydraulic jump does below small hydraulic
structures. In the present study a series of laboratory experiments were performed in
order to determine the effect of inclination of the screen on the energy dissipated by
the screen. The porosity of the screen used in the experiments is 40%. Inclination
angle, thickness of the screen, location of the screen, upstream flow depth, and the
Froude number of the upstream flow are the major parameters for the laboratory
experiments. Froude number of the upstream flow covered a range of 5 to 24. A
screen was located up to a distance 100 times the undisturbed upstream flow depth
from the gate and the thickness of the screen was changed in correlation with the
depth of upstream flow. The results of the experiments show that the inclination
parameter has an insignificant effect on the energy dissipated by the screen. Namely,
inclination of the screen does not contribute much in reducing the energy of the
flowing water further, compared to vertically placed screens.
