Spur-dikes are efficient hydraulic structures that made for numerous purposes. They have one end on the stream bank and another extending into current. As a result of existing spur-dikes in course, local scour phenomena usually occur around them, leading to several predicaments which been great concern engineers. For present work, laboratory experiments were carried out measure depths located a...

Abstract Flow in streams and rivers typically erodes the banks, causing channel bank migration laterally, resulting loss of nearby land, modification morphology, excessive sediment transport, water quality degradation. A spur dike is a hydraulic structure placed at projecting outward to guide or divert flow away from bank, thus protecting it erosion. The stability riverbed banks influenced by t...

Spur dikes are well-known structures that widely used in rivers and coastal regions. Depending on their types, sizes, orientation angles, spur can substantially change flow characteristics. Results of previous studies indicate the presence an ice cover cause complicated structures. The present experimental study investigates velocity fields turbulence vicinity under with different roughness coe...
