Projected future habitat of coastal wetlands in the Nisqually River Delta, Washington This dataset consists of raster geotiff outputs from modeling vertical accretion and carbon accumulation in the Nisqually River Delta, Washington, USA. These rasters represent projections of future habitat type, change in surface elevation above Mean Sea Level, and total sediment carbon accumulation since 2011 in coastal wetland habitats. Projections were generated in 20-year increments for 100 years for five amounts of sea-level rise, three amounts of suspended sediment concentrations, and two alternative configurations of the U.S. Interstate-5 causeway as it crosses the Nisqually River to either prevent or allow inland habitat migration (a total of 30 scenarios). The full methods and results are described in detail... Tags: Brackish Marsh, Emergent Tidal Wetland, Estuarine Coastal, Freshwater Tidal Marsh, High Salt Marsh, All tags...

The model was run across a range of initial elevations for each region and for scenarios of sea-level rise (30, 61, 91, 122, 152, 183, 305 cm by 2100), sediment availability (historic, constant, declining, and increase), and with and without a temporally dynamic tidal range. Results from the Delta Simulation Model 2 hydrodynamic model were used to calculate rates of tide range increase with sea-level rise. WARMER-2 was calibrated using soil cores from Callaway et al 2012 (Rush Ranch and Browns Island cores), and a soil core from Miners Slough. ...
