Prediction of Location of Abutment and Contraction Scour Hole for Compound Channels
Publication: World Environmental and Water Resources Congress 2018: Hydraulics and Waterways, Water Distribution Systems Analysis, and Smart Water
ABSTRACT
Bridge scouring is a complex phenomenon, responsible for bridge damage and failure in many cases. Numerous studies have given empirical models for the bridge scour components, whereas, some investigators have studied the interactive bridge scour relationship. However; the location of the bridge scour has not been given due attention which affects the bridge stability and design and also governs the design of downstream structures. A detailed investigation has been conducted to study the location of point of deepest scour in the floodplain in a compound channel, which includes free, submerged orifice flow, and overtopping flow conditions. Experiments were conducted for five different abutment ratios in clear water scour condition for erodible spill-through abutments. Location of the point of deepest scour, both in flow and transverse direction were observed and model has been suggested to predict the location of point of deepest scour. This will help improve the bridge safety and economy along with the effect of scour on river training works in the vicinity of bridge.
