Comparative study of local scour methods at bridge piers in the toribio river

, 2023
Local scour is a morphological process originated by the presence of a foreign object or an obstacle within water flow alignment; therefore, bridge piers act as the cause of this phenomena, generating a significant bed level change in a river´s cross ...

Mechanics of local scour: supplement, methods of reducing scour

, 1966
The purpose of this report is to summarize the results of tests conducted at Colorado State University on the hydraulic feasibility of reducing scour by modifying pier shapes. The following models were investigated: 1. Sharp nosed piers. 2. Rectangular pier on flat footing supported on piles. 3.

Detecting scour and liquefaction using OBS sensors [PDF]

, 2016
This work examined the performance of Optical Back-Scatter (OBS) sensors for detecting sediment movement around a model subsea structure. Three types of tests were conducted using a circular cylinder model equipped with 16 OBS sensors.

Local scour at wide bridge piers

, 2014
Laboratory data for local scour depth at the size of wide piers are presented. Clear water scour tests were performed various pier widths (0.06, 0.076, 0.102, 0.14 and 0.165 m), two type of pier shapes (circular and rectangular) and two types of uniform ...

On local scour around spur dikes

, 2000
Estimation of possible maximal scour depth around the head of spur dikes is an important step in the design of spur dikes foundation. This paper briefly analyses the characteristics of flow pattern and the complex eddy structure near the head of the spur

Scour-inducing flow around gravity anchors astride pipelines in currents

, 2014
This study simulated steady currents travelling past gravity anchors astride pipelines wallmounted on an immobile bed. Three-dimensional governing equations were solved with a Petrov–Galerkin finite element method.
