Experimental Study and Prediction Maximum Scour Depth Equation of Local Scour Around Bridge Pier

Scour is a problem which happen in the flowing stream, rivers and it’s a natural phenomenon made due to the erosive action of which removes the sediment particles around the structures placed in water. It means the lowering of the riverbed level by water erosions such that there is a direction to reveal structural foundations. The flowing water cause erosive action, excavating and relocate material from the bed and banks of streams and from around the piers of bridges. In this paper an attempt is made to evaluation the temporal variation of scour depth at non-uniform cylindrical bridge pier, in this paper 3 samples of circular bridge piers tested with different size which conducted in a 8.3 m length and 0.8 m width cannel by analyzing the data from experimental work analyzing the data to estimate equation which predict maximum scour depth.
