Figure 5: Wetland vegetation changes due to variable sea-level rise and variable soil surface elevation change with high suspended sediment.

(a,c) With the increased sediment availability bathtub model results indicate that the wetland withstands sea-level rise, with no loss of vegetation predicted. (b,d) The hydrodynamic model results still predicts considerable wetland loss, with about 70% of vegetated area loss after 80 years. However, due to increase sediment availability the rate of vegetation loss is half the rate of the low suspended sediment simulations of Fig. 4. For complete results see Supplementary Figs 6 and 7.
