Figure 2 – Maps of the fraction of time any cell which is part of the channel network during the second half of the run remains part of the channel network. Cells with a value of zero are never channels, and cells with a value of 1 are always channels. For the top row (a–d)Qs = 2 m3/s, for the middle row (e–h) Qs = 1 m3/s and for the bottom row (i–l) Qs = 0.5 m3/s. The first two columns are unvegetated runs and the third and fourth are vegetated. The first and third columns haveQw = 2000 m3/s and the second and fourth have Qw = 1000 m3/s.
