Numerical study on the effect of the spur dikes on sedimentation pattern
Ain Shams Engineering Journal, 2018 The spur dikes are structures that usually used for flow diversion from erodible wall and they usually create a appropriate path for directing the flow, flood control, protection of external walls, and some other cases.

Tidal Bore Scour around a Spur Dike
Journal of Marine Science and Engineering, 2022 Tidal bores are a natural phenomenon with high flow velocity and destructive potential. A spur dike is a widely used river regulation and embankment protection structure that minimizes erosion, promotes deposition, and protects riverbanks.

Riverbed Morphologies Induced by Local Scour Processes at Single Spur Dike and Spur Dikes in Cascade
Water (Switzerland), 2023 Spur dikes are elongated structures extending from banks into rivers that mitigate erosion by forcing the flow away from the bank. The research on grouped spur dikes is insufficient in comparison with those on isolated spur dikes. Most of the studies focus on the maximum scour depth, omitting the bed morphological changes induced by local scour ...

Influence of Spur Dike on Flow Patterns in an Open Channel [PDF]
Mehran University Research Journal of Engineering and Technology, 2013 Spur dikes are used for river protection purposes. They are typical in-stream structures. There existence results in a considerable change in the flow structure of open channel flow both upstream and downstream of the spur dike.
