Sediment deposition in a rigid monsoon drain

Field data collections to study the physical sediment characteristics and trends of sediment deposition were carried out at Raja River monsoon drain made up of concrete channels for the period of 2000 and 2001. Assessments of the existing incipient motion equations developed from experimental works were made using the measured field data. The results show that equations by Novak & Nalluri (1975), El‐Zaemey (1991) and Ab. Ghani et al. (1999) are able to predict satisfactorily the sediment deposition in rigid channel.
