Colville River Delta Sea Ice Model and Output Data Files

In this study, we used a 1D Delft3D-FLOW model to simulate the temporal development of the Colville River Delta, AK during the most active Arctic seasons. Simulations focused on the deltaic clinoform (i.e., the cross-sectional view of a delta) and used a floating barge structure to mimic the effects of sea ice on surface waters. Delft3D simulations were coupled with modules written in MATLAB and outputs were process in MATLAB.

The dataset includes an example model run file (Delft3D-FLOW and MATLAB) and output of results from simulations used to assess Arctic delta development under sea ice.  

Files include:

1. Example Delft3D-FLOW model setup file, MATLAB run script, and ice files for a 1500-year simulation.
2. Processed MATLAB structures and metadata for model results
   1. Long-term Delta Developmental Outputs (1500-year simulations)
      1. Ice-free
      2. Ice-affected
      3. Ice-free with waves
      4. Ice-affected with waves
   2. Varying Sea Ice Characteristics Outputs (500-year simulations)
      1. Ice matrix (six simulations)
   3. Future Arctic Delta Scenarios Outputs (450-year simulations)
