Abstract:

A simple numerical model, written in Matlab, to simulate the long-term morphological evolution of marshes with ponds. The model is described in: Mariotti G. (2016) Revisiting salt marsh resilience to sea level rise: Are ponds responsible for permanent land loss? JGR-Earth Surface. 121(7): 1391-1407 DOI: 10.1002/2016JF003900

Purpose:

Predicting thresholds for salt marsh loss
