Abstract

The protection of river bank, especially in a channel bend, is important because it has been observed more scour in the outer bank of bend. The previous experimental studies were almost about scouring around the bank protection structures and less attention were paid to FLOW PATTERN around transverse structures in rivers. In this study the effect of RELATIVE RADIUS of channel bend on flow behavior and FLOW PATTERN around a T-shaped spur dike located in section 45o of a 90 DEGREE BEND was investigated. Three RELATIVE RADIUS of bend: R/B=2, 3 and 4 were studied. It was found that the FLOW PATTERN around a T-shaped spur dike is accompanied with two counter clockwise vortices at the upstream and downstream of the spur dike. Also increasing the RELATIVE RADIUS of channel bend increases the length of SEPARATION ZONE, the upstream vortex and decreases the width of SEPARATION ZONE, the length of circulation zone and the downstream vortex.
