Abstract
The characteristics of hydraulic jumps were investigated for three shapes of artificial apparent
corrugated beds in a horizontal rectangular flume. Rectangular, triangular, and circular-shaped tire
waste corrugated beds were used. Froude number ranged from 2.75 to 4.25. The experimental
observations included water surface profiles, bed shear stress, and the hydraulic jump length. Results
showed that the shape of the corrugation had relatively insignificant effects on hydraulic jump
properties for small Froude numbers. The rectangular, triangular, and circular-shaped corrugated beds
reduced the hydraulic jump length by up to 7, 10, and 11%, respectively. The corrugated bed also
reduced the tailwater depth by up to 11.5% compared with the smooth bed. The apparent conditions
of corrugated bed reduced the hydraulic jump relative length and height by about 0.4 and 0.5,
respectively. The circular-shaped tire waste was found to be more effective in reducing the length and
depth of the hydraulic jump.
