Figure 1. a) R (the rate of decay in remaining delta surface
unreworked by the channel network), b) average number of channels,
average over the second half of the run and counted along the arc of a
semicircle with 2/3 of the delta’s area c) M (the rate of decay
in channel planform overlap), d) shoreline roughness (measured as
shoreline length divided by the square root of delta area). Panels are
plotted against Qw , withQs represented by increasingly dark shades of
orange (for unvegetated deltas) and green (for vegetated deltas). In
panel c, there is only one value of M and 2 values of Rfor the Qw = 1000, Qs = 2
vegetated condition (explanation found in Table 2 and Figure S1).
