Abstract: Bridge pier as a crucial part of a bridge is used for various marine and transportation purposes. Local scouring around the bridge pier is a prominent cause which leads to the failure of the bridge system. scouring around the bridge pier is caused due to the effect of vortices created by water current. To prevent scouring we have to design the countermeasures and also maintain the sediments which are erodible. This review examines both type of countermeasure devices. Measures such as to divert the flow or to strengthen the river bed. Use of slot can reduce the scouring to 20% and with combination of collar and slot the reduction efficiency increases. Use of rip rap strengthens the river bed and reduces the scouring. Both the measures are different in their aspects and can be used to reduce scouring. Various countermeasures used together can reduce the scouring effectively.
