Bridges are symbols of a country’s infrastructure. In order to link people, products, and transportation, bridges are necessary. A nation’s economic development can be halted by the closing of a bridge. It is possible to finish services that are no longer provided by bridges. Bridges are used to move cargo and resources from one location to another. Over bridges, one can get away from the bustle of daily life. The things might be delivered by customers. Due to the increase in the world’s population, the bridges are constructed in close proximity to each other. Due to close proximity, it can significantly affect the scour depth of the bridge piers. The present paper discusses the effect of a group of piles on the scour depth of an isolated bridge pier. A typical 12 m long, 0.60 m wide, and 0.70 m deep tilting bed water flume was used for the experiments. The pier models that were utilized were 42 mm and 62 mm in size. The uniform-sized river sand utilized in the movable bed studies had an average mean size of d₅₀ = 0.23 mm. From the experimental results, it can be observed that when two rows of groups of piles are placed in front of the isolated bridge pier the scour depth around the bridge pier is found to be minimum.
