The erosion of earth material at bridge foundation establishment by streaming water, velocity of stream surpasses the constraining speed, the scour occurs. Scouring is leading cause for bridge failure. Generally abutment are scour basic and around 60% bridge failure worldwide have been directly or by implication brought about by scouring. Scour at bridge abutment can caused harm or disappointment of bridge and result in unreasonable fixes, loss of openness, and so forth. Any under estimation of scour may bring about disappointment of bridge while over estimation will prompt acceleration of expense. The review recognizes and assesses driving scour recipes and propose a system for building up a unified projection driving scour equations and recommend a structure for building up an assembled projection scour recipe that relies upon fulfilling a few focused on future research needs. This project will estimate the risk of scour bridge failures by integrating experiments, numerical and theoretical research.
