Flow structure and scour around circular compound bridge piers – a review

, : Flow structure and scour around circular compound bridge piers – a review. Journal of Hydro-environment Research 6(4): 251-265

Large amount of literature is presently available on the topic of scour around uniform piers and its control. However, relatively fewer studies have been carried out so far on the topic of flow field and scour around compound piers. The state of art on the topic of flow structure and scour around circular compound piers is presented herein. The available literature reveals that variations in foundation and pier geometry significantly affect the maximum depth of scour and its temporal variation. In case of compound piers the scour depth is highly sensitive to the change in elevation of the top surface of the foundation well. As compared to uniform piers, a reduction is observed in maximum depth of scour around compound pier when the top surface of the well is kept below the general level of river bed. These observations however are yet to be quantified. from an experimental study on flow field around the compound piers are also presented. The state of art on the topic of flow structure and scour around circular compound piers is presented herein. from an experimental study on flow characteristics around the circular compound bridge piers are presented. The temporal variation of depth of scour around circular compound bridge piers has been quantified. Slight alterations in the level of footing top surface would significantly affect the bridge pier scour. The aspect related to placing of the footing thus needs to be effectively quantified.
