RISThe effect of pile spacing and arrangement on bed formation and scour hole dimensions in pile groups
Pile scour is the main cause of bridge failure. A physical model used in this research to study scour
around a group of piles in clear-water conditions. The study examined changes in stream bed,
volume and area of scour holes due...
Experimental investigation of clear-water local scour at pile groups
Experiments of local scour around pile groups are carried out under steady clear-water scour conditions. A variety of conditions including different pile group arrangements, spacing, flow rates, and sediment grain sizes are considered. In total, 112...
Discussion of “Clear-Water Local Scour around Pile Groups in Shallow-Water Flow”
The article focuses on the discussion of the article \\"Clear-Water Local Scour around Pile Groups in Shallow-Water Flow,\\" by Ata Amini and colleagues. It says that the experimental results of scour measurements around pile groups with different...
Scour hole depth prediction around pile groups: review, comparison of existing methods, and proposition of a new approach
A dataset of 365 laboratory tests for scour hole depth (SHD) around pile groups (PGs) under unidirectional aligned flow is compiled, and the performances of the existing equations are comparatively evaluated on the dataset using several statistical...
Experimental Study of Three-Dimensional Flow Field around a Complex Bridge Pier
In this paper, three-dimensional turbulent flow field around a complex bridge pier placed on a rough fixed bed is experimentally investigated. The complex pier foundation consists of a column, a pile cap, and a 2×4 pile ...
Discussion of an integrated framework of extreme learning machines for predicting scour at pile groups in clear water condition by: I. Ebtehaj
In this comment we showed the flaws in data,
method, and results of Ebtehaj et al. (2018). More importantly, we
would like to remind the readers about the abuse of the powerful and
valuable soft computing ...
LS-SVM and FCM assessment approach in estimation of pipeline scouring on a river bed
The mechanism of flow around a circular structure such as pipeline is very complicated so that it is difficult to establish a general empirical model to provide accurate estimation for scour. River bed deformations due to underwater pipeline scour...
Comparison between the circular and square collar in reduction of local scouring around bridge piers
In this study operation of two types of circular and square collars has been investigated on a single cylindrical pier. The results showed that using of these two types of collars cause to reduction of scour depth especially under...
