Abstract

The goal of this paper is, study the effects of creating the surface WAVEs in a UNIFORM FLOW on BED LOAD TRANSPORT RATE of deposited sediment in a Primal RIGID RECTANGULAR CHANNEL. Experiments were carried out in a rectangular flume of 10m length, 0.2m width and 0.3m height, for two gradations of sediments with median diameters of 0.34 and 0.48 mm and specific weight of 2.67, and for five BED SHEAR STRESSes (initiation of motion and multiplies of 1.16,1.25,1.39 and 1.43 of it for median diameter of 0.34 mm and initiation of motion and multiplies of 1.15,1.25,1.33 and 1.41 of it for median diameter of 0.48 mm) and two WAVE heights (1 and 1.6 cm) with four WAVE speeds. The results showed that creating surface WAVEs increases the BED LOAD TRANSPORT RATE. Furthermore, the BED LOAD TRANSPORT RATE increases with Strouhal number, dimensionless WAVE height and BED SHEAR STRESS. It can be concluded that creating artificial WAVEs can increase the BED LOAD TRANSPORT RATE in a RIGID RECTANGULAR CHANNEL up to 280% compared to the no WAVE conditions.
