Figure 2. Relationships between sediment transport and geomorphic metrics.

Figure 2

(a) Ratio of unvegetated to vegetated marsh (UVVR) within the tidal channel drainage area versus net sediment budget (sediment flux minus supply needed to offset SLR) and (b) UVVR versus sediment-based lifespan of the marsh complex. Individual points are coloured to represent local sea-level rise. Regression statistics apply to fitted curves to data: (a) y=−0.42 ln x−1.07; and (b) y=48x−1.66. Error bounds correspond to potential uncertainty in (a) drainage area and UVVR; and (b) bulk density and UVVR. Note that sites with nearly zero sediment flux exhibit smaller errors in net sediment budget (a) due to a greater influence of the sea-level rise term.
