Integrative Study on Flow Characteristics and Impact of Non-Submerged Double Spur Dikes on the River System [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2023
The flow characteristics around non-submerged spur dikes continuously placed in the channel on the same side with orthogonal angle to the wall were investigated by numerical simulations and experimental measurements. Three-dimensional (3D) numerical simulations with the standard k−ε Model for incompressible viscous flow based on finite volume method ...

Estimation of scour depth at a single non-submerged vertical spur dike under unidirectional currents

open access: yesWater Science and Engineering
Accurately estimating equilibrium scour depths at spur dikes remains challenging due to the complexity of scour around these structures. Scour critically threatens spur dikes built in river estuaries for enhancing navigability and preventing bank erosion.

Effect of the Flow and Geometric Parameters of Submerged Spur Dike on Riprap Stability [PDF]

open access: yesعلوم آب و خاک, 2017
Spur dikes are the most common hydraulic structures for river bank protection. Since the construction of this structure causes higher velocities around it, this structure is exposed to erosion.

Exploring Proper Spacing Threshold of Non-Submerged Spur Dikes with Ipsilateral Layout [PDF]

open access: yesWater (Switzerland), 2020
Concerning the clustering of spur dikes on river systems, the spacing thresholds of twin spur dikes are important parameters to influence the estimations on the impact scales of spur dike groups and the overall responses of river systems. In this study, both numerical investigations and experimental measurements are proceeded to quantify the influence ...

CFD technology in innovative spur dike design inspired by the Eğri (curved) Bridge [PDF]

open access: yesScientific Reports
In 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.

The Effect of Relative Spur Height and Length on The Riprap Stability Around The Submerged Spur Dike in a 90° Bend [PDF]

open access: yesعلوم و مهندسی آبیاری, 2015
Spur dikes are hydraulic structures, which are built across the river from river bank towards centerline in order to protect the river bank from erosion, natural development of amending the river side, special protection of local structures, navigation ...

Experimental Study of the Effect of Spur Dike Permeability and Angle on Scour Hole Dimensions in Non-Submerged Conditions [PDF]

open access: yesعلوم و مهندسی آبیاری, 2016
Spur dike is a hydraulic structure which has an essential role in reducing the shear force on river banks. The interaction between the structure and flow makes vertical and horizontal vortices, which are the main reason for producing a local scour hole ...
