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 ...

Estimation of Maximum Scour Depth and Scour Pattern Around Submerged Spur-Dike [PDF]

open access: yes, 2022
Scouring due to turbulent flows is a process that naturally happens around river structures, including river training or riverbank protection works such as spur dikes, submerged vanes, etc.

Experimental study of layout of spur dike as ice-proof structure in curved channel

open access: yesShuili Shuiyun Gongcheng Xuebao, 2018
The concave bank of curved channel is easily eroded or collapsed under the impact of ice floes, and its bank revetment will also be damaged and lose its function of protection under the impact of ice floes.

Experimental Study on Effects of Permeability and Spur Dike Series Length on Scour-Hole Dimensions in a 90° mild bend under non-submerged conditions [PDF]

open access: yesعلوم و مهندسی آبیاری, 2017
River changes happen due to the periodic erosion and sedimentation along river bed, destruction and widening of river banks, movement of the meandering pattern and flow direction, changing of river form (braided, sinusoidal, and straight), and shortcut ...

Velocity Distributions around a Spur-Dike

open access: yesPROCEEDINGS OF HYDRAULIC ENGINEERING, 1995
In river planning, it is necessary to study the influence of river construction to the river flow and the river bed. A flow affected by the river construction is a three-dimensional complicated flow.Sand deposition and scour around the construction is caused by this complicated flow which make it difficult to grasp the river change with the ...

Investigation of the Effect of Increasing the Wing Length of the L – Shape Spur Dike on the Scouring Around in the 90 Degree Bend [PDF]

open access: yesعلوم و مهندسی آبیاری, 2014
Spur dike is one of the conventional structures in organizing and controlling erosion on the river side slopes. It causes the strong flows to be taken away of coastal and flow is guided towards river axis.

Experimental Investigation on 3D Flow around a Single T-Shaped Spur Dike in a Bend [PDF]

open access: yes, 2017
The flow field around a T-shaped spur dike located in a 90° bend is investigated experimentally. The three-dimensional Acoustic Doppler Velocimeter (ADV) was used for measuring the flow field.
