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.

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 ...

Scour process, flow dynamics, hydrodynamic forces, around a series of repelling spur dikes [PDF]
Scientific ReportsThis experimental study examined the turbulence effects around spur dikes on scour dynamics under clear-water conditions. An experiment was conducted in a straight rectangular flume of length, width, and flow depth: 15, 0.91, and 0.70 m, wherein ...

Numerical Simulation of the Influence of Spur Dikes Spacing on Local Scour and Flow
Applied Sciences (Switzerland), 2019 The spacing of spur dikes is an important consideration for the layout of spur dike channels. This study focuses on the local scour morphology and flow field characteristics of spur dikes with different spacings.

Study on Spacing Threshold of Nonsubmerged Spur Dikes with Alternate Layout [PDF]
Journal of Applied Mathematics, 2013 This paper investigated the spacing threshold of nonsubmerged spur dikes with alternate layout to classify the impact scale of spur dikes. A mathematical model was built based on standard k-ε model, finite volume method (FVM), and rigid lid assumption ...

CFD technology in innovative spur dike design inspired by the Eğri (curved) Bridge [PDF]
Scientific ReportsIn addition to consuming, using, and benefiting from it, it has sometimes become necessary to establish defense mechanisms against water. In particular, precautions against floods, torrents, and sediment transport in the flow have been essential.

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.

The Effect of Percentage Permeability in Composite Structure of Spur dike with Vane on a Sedimentation Pattern in 180̊ mild curve [PDF]
علوم و مهندسی آبیاری, 2023 One common method for Blank River protection and restoration is use of Spur dikes. Spur dikes either in the forms of group or single, depending on their permeability is classified an permeable and impermeable.
