|a Early comparisons between rates of vertical accretion and sea level rise across marshes
in different tidal ranges inspired a paradigm that marshes in high tidal range environments
are more resilient to sea level rise than marshes in low tidal range environments. We
use field‐based observations to propose a relationship between vegetation growth and tidal
range and to adapt two numerical models of marsh evolution to explicitly consider the
effect of tidal range on the response of the marsh platform channel network system to
accelerating rates of sea level rise. We find that the stability of both the channel network
and vegetated platform increases with increasing tidal range. Our results support earlier
hypotheses that suggest enhanced stability can be directly attributable to a vegetation
growth range that expands with tidal range. Accretion rates equilibrate to the rate of sea
level rise in all experiments regardless of tidal range, suggesting that comparisons
between accretion rate and tidal range will not likely produce a significant relationship.
Therefore, our model results offer an explanation to widely inconsistent field‐based
attempts to quantify this relationship while still supporting the long‐held paradigm that
high tidal range marshes are indeed more stable. |
