Describe processes represented by the model Sea-level rise, alongshore sediment transport, and tidal-driven sediment transport on barrier islands, resulting in storm-overwash, tidal inlet formation, migration, and closure, and barrier transgression
Describe key physical parameters and equations
Describe length scale and resolution constraints Coastal barrier ~10-100 km length scales, and ~100 m alongshore resolution. Parameterizations not suitable for small-scale (tidal inlet etc) analyses
Describe time scale and resolution constraints sea-level rise timescales (decades to millennia). Parameterizations not suitable for short-timescale analyses
Describe any numerical limitations and issues
