Self-cleansing is a design criterion for drainage systems that mitigates the continuous
deposition of sediments at the channel bottom. In recent decades, in order to improve the …

Sediment transport in sewers has been extensively studied in the past. This paper aims to
propose a new method for predicting the self-cleansing velocity required to avoid permanent …

The necessity of sewers to carry sediment has been recognized for many years. Typically,
old sewage systems were designated based on self-cleansing concept where there is no …

The application of models capable of estimating sediment transport in sewers has been a
frequent practice in the past years. Considering the fact that predicting sediment transport …

It has been known that the channel cross-section shape impacts on flow velocity at sediment
deposition condition; however, existing models only apply to specific cross-section shapes …

Mitigation of sediment deposition in lined open channels is an essential issue in hydraulic
engineering practice. Hence, the limiting velocity should be determined to keep the channel …

It is known that construction of large sewers based on consideration of flow with non-
deposition without a bed deposit is not economical. Sewer design based on consideration of …

Old sewerage systems were designed based on empirical rules to minimize sediment
problems and a list of codes for self-cleansing sewers. These codes were applicable to …

The minimum velocity required to prevent sediment deposition in open channels is
examined in this study. The parameters affecting transport are first determined and then …

This study of bed-load transport was undertaken on the basis of laboratory data in two
states, ie, limit of deposition and deposited bed, by using new design criteria, whereby …
