SEDIMENT TRANSPORT OF LOW CONCENTRATION IN PIPES |
|
| Abstract: | The study of Sediment transport of low concentration in pipes bas been applied in the design of a self-cleansing storm sewer. An alternative criterion is suggested as op- posed to the widely used single flow velocity approach. A conceptual model which simu- lates the condition in a storm sewer is developed and tested against experimental data. The results proved that the volumetric sediment concentration, pipe diameter and sedi- ment size have to be taken into consideration to produce a self-cleansing storm sewer. It also shows that the slope obtained by this alternative criterion is lower than the single flow velocity approach. |
