Study of Scour Around Spur-Dikes

Journal of the Hydraulics Division, 1961
Investigation was conducted in 2 ft wide by 25 ft long nonrecirculating flume; effect of flow, spur-dike, and sediment characteristics on maximum scour depth; it was found that Froude number of normal channel, opening ratio, angle of inclination of spur-dike, and average drag coefficient of sediment particle adequately represent influence on maximum ...

Backwater effect due to a single spur dike

Canadian Journal of Civil Engineering, 2007
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 of the riverbank from erosion. A spur dike might be considered a form of macroscale boundary roughness, which produces a backwater effect upstream from the spur dike ...

Scour around impermeable spur dikes: a review

ISH Journal of Hydraulic Engineering, 2017
AbstractScour is a natural process in rivers initiated by the erosive action of the activated water. Spur dikes are built across the flow to defend the stream erosion and facilitate the shifting of the river away from the bank. The spur dike weakens due to stream bed scouring and erosion, which is usually documented as the key reason of spur dike ...

Local scour around spur-dikes

Journal of Hydrology, 1983
Abstract Experimental investigations were conducted to study the effects of upstream flow conditions, sediment characteristics, and spur-dike's geometry on the maximum scour depth and scour pattern around a spur-dike. Dimensional analyses to find different non-dimensional terms affecting the phenomenon were obtained and verified with the help of the ...

Local Scour Associated with Angled Spur Dikes

Journal of Hydraulic Engineering, 2002
A series of experiments were conducted in which the volume of the scour hole associated with model spur dikes was measured in a laboratory flume under clear-water overtopping flows. Spur dike models were angled at 45, 90, and 135° to the downstream channel sidewall with contraction ratios of 0.125 and 0.250.

Scour around spur dikes and bridge abutments

Journal of Hydraulic Research, 2001
Realistic estimation of scour depth around spur dikes and bridge abutments in alluvial rivers is important for safe and economic design of their foundations. Procedures have been developed by previous investigators for determination of design scour depth in steady flows at abutments and spur dikes by making use of the design discharge.

Geometry of Scour Holes Associated with 90° Spur Dikes

Journal of Hydraulic Engineering, 1999
The stable pools formed by spur dikes can be a significant factor for improving aquatic habitat in unstable degraded streams. Prediction of the volume and geometry of the scour hole associated with a spur dike yields information that is valuable for assessing the potential benefit to the aquatic habitat.

Erosion of Sand Beds around Spur Dikes

Journal of the Hydraulics Division, 1972
The present status of research on erosion of sand beds around spur dikes is briefly reviewed. The experimental results of erosion of two different sizes of nearly uniform sand are presented. It is shown that a rather simple kinematic model for erosion of sand beds in a long contraction, first proposed by Straub, can be modified for application to ...

Application of Permeable Spur Dike in Mountain River Training

Applied Mechanics and Materials, 2014
Based on the investigation and indoor experiment, the flow structure and properties of erosion or deposition associated with permeable spur dike were researched. According to the new demands about engineering structure in mountain rivers regulation, the potential action of permeable spur dike in mountain river training was analyzed.

Bank Protection Techniques Using Spur Dikes

2023
A Hydraulic Model Investigation was conducted to evaluate and demonstrate the effects of impermeable spur dikes as a bank protection technique in a concave bend. The tests were conducted to observe channel bed and bank response in a stream with noncohesive banks where suspended load is insignificant. Several parameters relative to spur dike design that
