Abstract

Model results suggest that 1) varying lateral bed-slope factor has strong impacts; larger value leads to gentler channel-shoal interface or smaller lateral channel bedslope. 2) Different sediment transport formulas lead to considerable differences in morphodynamic patterns. 3)
Sediment transport formulas considering both
suspension and bed load transport tolerate a smaller
morphological acceleration factor and requires a larger
bed-slope factor.
