Backbarrier marsh widths derived from GEOMBEST++ simulations of barrier island/marsh evolution

Backbarrier marsh widths derived from GEOMBEST++ simulations of coupled barrier island-marsh evolution. Input parameters varied were overwash flux (m^3/yr), initial marsh width (m), and BAR/RSLRR: the ratio of basin accretion rate to relative sea level rise rate (mm/yr). The basin accretion rate is obtained by dividing the bay sediment flux (m^3/yr) by the initial basin width. Overwash flux ranged from 0.2-20 m^3/yr in increments of 0.6. BAR/RSLRR ranged from about 0.1 to 10 with 5 values evenly spaced on a log scale. Each combination of overwash flux and BAR/RSLRR was run with an initially narrow marsh and with an initially full basin, resulting in 40 total simulations. Each simulation was run for 1 m of sea level increase. Each row in the spreadsheet lists inputs and outputs for a single simulation. Outputs reported here are the final backbarrier marsh width and the change in marsh width.
