• Abstract:
  The present study is an integral part of a
  
  broader study focused on the design and
  
  implementation of self-cleaning culverts, i.e.,
  
  configurations that prevent the formation of
  
  sediment deposits after culvert construction or
  
  cleaning. Sediment deposition at culverts is
  
  influenced by many factors, including the size
  
  and characteristics of material of which the
  
  channel is composed, the hydraulic
  
  characteristics generated under different
  
  hydrology events, the culvert geometry
  
  design, channel transition design, and the
  
  vegetation around the channel. The multitude
  
  of combinations produced by this set of
  
  variables makes the investigation of practical
  
  situations a complex undertaking.
  
  In addition to the considerations above, the
  
  field and analytical observations have revealed
  
  complexities of the flow and sediment
  
  transport through culverts that further
  
  increase the dimensions of the investigation.
  
  The flow complexities investigated in this
  
  study entail: flow non-uniformity in the areas
  
  of transition to and from the culvert, flow
  
  unsteadiness due to the flood wave
  
  propagation through the channel, and the
  
  asynchronous correlation between the flow
  
  and sediment hydrographs resulting from
  
  storm events. To date, the literature contains
  
  no systematic studies on sediment transport
  
  through multi-box culverts or investigations
  
  on the adverse effects of sediment deposition.
  
  Similarly, there is limited knowledge about
  
  the non-uniform, unsteady sediment transport
  
  in channels of variable geometry.
  
  Furthermore, there are few readily useable
  
  (inexpensive and practical) numerical models
  
  that can reliably simulate flow and sediment
  
  transport in such complex situations.
