Scour Evolution Downstream of Submerged Weirs in Clear Water Scour Conditions
Water (Switzerland), 2019 Although weirs or dikes in the riverine and coastal environments are frequently overtopped, few studies have hitherto examined the evolution of the scour process downstream of these structures under the submerged condition. This paper presents an experimental investigation on time evolution of the scour process downstream of submerged weirs with a ...

Temporal variation of clear-water scour at compound Abutments
Ain Shams Engineering Journal, 2016 Most of actual abutments in rivers are built on foundation, while there is limited number of study available on the effects of the foundation on the local scour.

Clear-Water Scour at Comparatively Large Cylindrical Piers [PDF]
Journal of Hydraulic Engineering, 2013 AbstractNew long-duration clear-water scour data were collected at single cylindrical piers with the objective of investigating the effect of sediment coarseness, Dp/D50 (Dp = pier diameter; D50 = median grain size) on the equilibrium scour depth and improving the scour depth time evolution modeling by making use of the exponential function suggested ...

Clear water scour around a finite array of cylinders
Applied Ocean Research, 2017 Abstract This experimental study presents clear-water scour and deposition patterns around hexagonal arrays of circular cylinders in steady flow conditions. Understanding the scour processes around such configurations could facilitate the design of several hydraulic and marine engineering structures, such as bridge piers and piles.

Clear Water Scour at Rectangular Bridge Pier with Collar [PDF]
Port Said Engineering Research Journal, 2023 Scour is the most significant threat to waterways because it leads to the failure of bridge piers and other structural components. When a collar is put in place around the pier to lessen the direct effect of the downflow on the streambed, the maximum ...

Potential of roughening geometric elements as bridge pier local scour countermeasures [PDF]
Scientific ReportsThe safety of bridges can be endangered by sediment erosion occurring around bridge piers. To mitigate this issue, this study examined the use of different roughening geometric elements (RGEs) on the upstream surface of bridge piers.

Experimental study of clear-water contraction scour
Water Science and Technology: Water Supply, 2020 AbstractIn this paper, experimental results of clear-water scour on a sand bed under short contractions were studied. Sequences of test runs were performed under clear-water conditions for three different contraction ratios. The outcomes of the experiments were employed to define the effects of various parameters on equilibrium scour depth under clear ...

Geometric Characteristics of Spur Dike Scour under Clear-Water Scour Conditions [PDF]
Water, 2018 Factors such as flow and sediment characteristics affecting the spur dike’s local depth of erosion have yielded considerable research results, but there is little discussion of the geometry of the spur dike’s local scour holes. This study focuses on the spatial characteristics of the geometry of local scour holes in straight-wall spur dikes.
