Abstract

The current experimental work deliberates for the parameters of jump downstream
Two Vertical Overlapping Gates (TVOG). The proposed TVOG allows dividing
the flow via two openings. The lower one is under the lower gate, while the upper
one is proposed between the gates. Experiments are examined on a rectangular
flume of 66 cm width, 65.5 cm depth and 16.2 m length. The ideal percentage of
the upper opening related to the lower one is detected experimentally. It is found
that, working TVOG by upper opening fifty percent of the lower one wastes the
flow energy by 52% and shrinks the basin length by 4.3%.
