Utilizing spur dikes is one of the common methods of organizing and controlling side erosion in river bends. In this research study the effect of permeability of spur dike on scour-hole dimensions was experimentally investigated in a flume with 0.7m width, having a 90 degree bend with relative curvature of 4.0 and water depth of 0.14m for non-submerged condition. The results indicated that for a constant Froude number, scour decreases significantly with increasing the percentage of spur permeability. For spur with 33% permeability the relative depth, length and width of scour-hole decreased 63.9, 38.1, and 35.5 percent, respectively in comparison with impermeable spur. The same results were obtained for spur with 64% permeability with 67.1, 88.2 and 53.8 percent, respectively.
