In this paper the effect of vortex formation
upstream inclined sluice gate, discharge coefficient as well as predicted
discharge equation have been studied for several gate openings (3,4&4.5)
cm, five discharges and three different gate
cases, vertical and inclined opposite flow
direction in (30 and 45)° angles.

It was found that there is no vortex at vertical
sluice gate but observed at gate inclined opposite flow direction. There are tow
corner vortices in high discharges and one central vortex in low discharges. The
reduction of these vortices has been studied by vortex decay elements.

The average discharge coefficient for
vertical gate was 0.645 while these values reduced to 0.59 and 0.564 for gate
inclined (30 and 45)° opposite flow direction respectively
