This paper presents, a set of experiments was conducted in a Plexiglas flume setup to investigate the
simultaneous use of pipe and blade in the scour control around a submerged pipe. A vertical cylindrical pipe
with and without a blade placed below it was selected for the experiments. The experiments were carried
out in two different sates: with blade and without blade the pipe. Moreover, they were performed for four
different pipe diameters, flow intensities, and blades where clear water was also used. The results showed
for all states that simultaneous installation of pipe and blade below it caused a substantial decrease in the
scour length. In other words, applying the blade produced a decrease in the scour length below the pipe
by 21 percent. Furthermore, in all states, simultaneous use of pipe and blade engendered a more increased
scour depth than the absence of the blade, by 22 percent. Besides, maximum scour depth for simultaneous
use of pipe and blade was obtained equal to 55 percent when the blade width, pipe diameter, and Froude
number were set to 1.24, 4.8 cm, and 0.42, respectively.
