Fig. 7.26 Snapshots of pebble distribution at different time points for bed configurations of a R ∞ ,
b R 1 , c R 2 , and d R 3
from the higher position to the lower position. The simulation results in Fig. 7.27
confirm this assumption. The pebbles move very uniformly in the horizontal direction. At about t = 150 s, there are almost no stagnated pebbles in the bed. This is
much better than the former configurations of {R n }, even for R 2 (Fig. 7.27).
