Abstract

The main objective of this research work is study to what extent sediment load can affect the sand bed channel geometry i.e. mean width, water depth and bed slope. It was found in this study, the bed slope increased regularly with the increasing value of sediment concentration. Statistical analysis was performed to get the relationship between bed slope and sediment concentration at different values of discharges, for canals having median particle size varied between 0.05 mm and 0.5 mm. 
Both water depth and mean width could decrease with the increasing value of sediment concentration for canals having median particle size ≤ 0.4 mm.
