• Abstract:
  The accumulation of sediments at culverts is a chronic operational issue, frequently occurring at multi-barrel culverts located in erosion-prone watersheds. Sediment deposits can develop rapidly, impairing the culvert’s capacity to convey design flows and potentially leading to damage to both transportation infrastructure (e.g., road and culvert overtopping) and upstream areas (e.g., flooding). Current culvert design protocols focus primarily on flood flow conveyance, with less attention given to assessing the potential for sedimentation due to the limited understanding of the complex erosion and transport processes leading to culvert sedimentation. Consequently, costly culvert cleaning is often required to maintain operational functionality.
