ASPECT RATIO TO MAXIMIZE SEDIMENT TRANSPORT IN RIGID BANK CHANNELS

Calculation of formulas and maximum sediment transport equations and water discharge equations for the optimisation of rectangular and trapezoidal channels with fixed slope. Higher aspects ratios are required to maximise sediment transport for channels conveying bed load than for those with a dominant suspended load. Example of the Renmin Shingli main canal (14 km) in Henan province (China).
