Abstract

Inclined drop is one of the supercritical flow producers used in open channels to reduce slope and elevation of the ground. Given that the application of horizontal and vertical screen in the downstream of this drop as an energy dissipater can be effective in the n Energy dissipation of flow, in the present study, 180 different experiments were performed to investigate the Energy dissipation of flow. The results showed that the angle of the drop had no marginal impact on Energy dissipation and the Relative depth of downstream of inclined drop equipped with a vertical screen, but increasing the porosity of screen caused enhancement in both parameters. Also, for the inclined drop equipped with a horizontal screen, by increasing angle and decreasing the porosity of screen, the Energy dissipation and Relative depth of downstream were raised. Also, for inclined drop equipped with a horizontal screen, by increasing the angle and decreasing the porosity of screen, the Energy dissipation and Relative depth of downstream were enhanced. For a constant relative critical depth, the Relative depth of downstream and the Energy dissipation of the inclined drop equipped with a horizontal screen considered the function of the Wetted length of screen and length of the drop. For vertical screen, it is only a function of screen porosity.
