Abstract:

© 2014 American Society of Civil Engineers. Culverts are built at a location in a waterway that crosses a road or railway. The narrowing cross section of waterway creates a limitation to flow passage and therefore blockage occurs during flood events with accumulation of debris at the inlet. The blockage of the culvert can accelerate bed scouring and consequently causes failure of the culvert. It subsequently produces high damage to private properties and public assets. This article concerns scouring at the outlet of partially blocked culverts. In this context the blockage of culverts is studied as an important factor in the scouring pattern of culverts. Therefore, experimental tests were conducted to investigate the effects of culverts blockage on scouring downstream of a culvert. The experimental program was designed to investigate the relationship between the maximum scour depth, blockage ratio of the culvert, and flow characteristics. The experimental tests were carried under nonblocked and partially blocked conditions. The sediment material used in this study was uniform noncohesive sand particles. Results showed that the scoured area and maximum scour depth increases in partially blocked condition compared with the nonblocked condition. The results were compared with the previous developed models, and it was found that the previous model predicts scouring depth less than the scouring depth at blocked condition.
