Sediment in Sewers - Research Leaves in England

Gustavo Perrusquía-1990-01-01-Chalmers Publication Library (Chalmers University of Technology)

TL;DRAbstract

Experiments were made in part-full pipes with a deposited sediment bed both at Hydraulics Research.Wallingford and the University of Newcastle upon Tyne in the United Kingdom.Tests were carried out using different pipe diameters.sand sizes and sediment thicknesses.Discharge rates.flow depths.sediment transport rates and bedform dimensions were measured.The aim of these studies was to gather information for an oncomming report on the effects that the relative flow depth.the relative sediment depth.the relative grain size.the pipe diameter (in other words: shape factors) and the bedform dimensions produce on the sediment transport in part-full pipes.The preliminary results showed that a functional relationship of the type El.= f(eII.)can be used to describe the transport capacity of such pipes.
