Abstract:

Scour at spur dikes and bridge abutments can cause damage or failure of bridges or levees and result in excessive repairs, loss of accessibility, or even death. In this paper, set of experimental tests, are presents with 20 cm length, with rectangular, trapezoidal and semicircular end shape of spur dikes with three discharges. It was found that the scours of spur dike with semicircular end shape are at least between trapezoidal and triangular end shape. Also pattern of sedimentation is different with various discharge and with increasing of flow rate, erosion got rise.
