• 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.
