Abstract :- The bridge is a crucial aspect for transportation in marine and land. The safety of the bridge is crucial for the safety of humans. Local scouring affects the safety of the bridge structure immensely. Scour depth estimation is done by the years-old method such as the Lacey-Inglis method in India, which only yields effective results for coarse sand. Codes provide overestimated depth for scouring, which increases the cost of construction. This review paper studies various methods to effectively estimate the scour depth. Scour monitoring is also a necessary aspect, and this paper studies various monitoring devices which can be used according to different sites and economic conditions. The most important condition is to minimize the scouring, and devices used to reduce scouring are classified in the paper. Scour monitoring and reduction, if done effectively, increases the bridge's life span and hence increases the safety of life.
