Investigating sediment supply impact on centennial saltmarsh biogeomorphic development with Demeter

Description

This repository contains a series of simulations to investigate the impact of (changing) sediment supply on the long-term biogeomorphic development (200 years) of saltmarshes (4 km2). The model used is Demeter (https://doi.org/10.5281/zenodo.7101535).  Each simulation output file contains: yearly bottom elevation maps (resolution of 5 m); yearly vegetation coverage maps (resolution of 5 m); yearly hydroperiod maps (resolution of 5 m); yearly exceeding bottom shear impulse maps (resolution of 5 m); vegetation distribution maps every 5 years (resolution of 50 cm). Each simulation is also processed to compute channel network characteristics with TidalGeoPro (https://doi.org/10.5281/zenodo.7153257), such as: maximum upstream channel length along channel network skeleton every 20 years (resolution of 5 m); total upstream channel length within tidal watershed along channel network skeleton every 20 years (resolution of 5 m); tidal watershed surface area along channel network skeleton every 20 years (resolution of 5 m); mean unchanneled path length within tidal watershed along channel network skeleton every 20 years (resolution of 5 m); channel cross-section width, depth and area along channel network skeleton every 20 years (resolution of 5 m); yearly unchanneled path length maps (resolution of 5 m).
