Spur dikes are stone spurs that extend into the stream from the bank to minimize erosion by forcing flow away from the bank. Two to five structures are typically placed in series along straight or concave bank lines where flow lines are roughly parallel to the bank.

Dikes, sometimes referred to as wing dams or spur dikes, are structures placed in a river to redirect the river's own energy to provide a variety of effects. The structures are usually...

Spur dikes (or groynes) are structures constructed projecting from a bank to protect the bank from erosion. These are widely used for the purpose of river training and serve one or more of the following functions: Training the river along a desired course by attracting, deflecting (or repelling) and holding the flow in a channel.

2019年8月31日 · As a typical waterway modification, the spur dike narrows the water cross section, which increases the flow velocity and flushes the riverbed. Meanwhile, it also protects ecological diversity and improves river habitat.

2024年2月29日 · Each experimental setup for a specific shape of spur dike consisted of three spur dikes arranged in series, creating a field of spur dikes within the test section. While previous studies have primarily examined single spur dikes, combining multiple spur dikes holds greater promise for river protection (Nayyer, Farzin, Karami, & Rostami ...

2022年12月9日 · A spur dike is a hydraulic structure placed at the channel bank projecting outward to guide or divert the flow away from the bank, thus protecting it from erosion.

2021年1月23日 · In this research, both permeable and impermeable spur dikes were investigated with varying permeability (25%, 37%, 49%, 62%, and 74%) to show its effect on the flow structure. At zh =3.5 cm (where z is the maximum flow depth, and zh is mid of flow depth), 3-D flow velocities and depth-averaged velocities were measured in the horizontal plane.

2020年8月24日 · As hydraulic structures, spur dikes are constructed perpendicularly to erodible river banks in an attempt to divert the flow toward the middle of the channel as a measure for reducing and controlling river bank erosion. The expansion of the scour hole at the tip of the spur dike can lead to structure failure.

Spur dikes are river engineering structures that project from the bank of a stream at some angle to the main flow direction. They are principally used for river training and protection...

2024年7月1日 · In this study, we propose a feasible strategy to enhance meander habitat environments by deploying non-submerged spur dikes on concave banks and submerged spur dikes on convex banks in meandering rivers.
