ABSTRACT
In this study, a new flow altering measures for river sedimentation management, triangular shaped vane, has been experimentally tested. The vane has a sloping crest that extends from the riverbank and forms a low angle with the outer bank. The vanes were attached to the outer bend at an angle of 30 degrees and tested at different vane spaces. The results show that the thalweg of the river bed was shifted toward the center of the river. Sediment was deposited between the vanes, and scour developed around the tips of the vanes. We concluded that the new technique effectively shifted the thalweg of the river from the outer bank toward the center of the river. The banks of the river were stabilized by the siltation of the sediment that occurred upstream and downstream of the vane. From the tests conducted here it was concluded that the vane distance should not selected greater than 5 times the effective vane length.
