Abstract

This resource includes a newly developed coastal cryohydrogeological model that simultaneously solves the coupled partial differential equations describing variable-density fluid flow and solute transport, and heat transfer with salinity-dependent freeze-thaw. This code was developed using the commercial code FlexPDE. Included in this resource are the scripts and initial condition files necessary to run various sea-level rise and warming scenarios for three values of intrinsic permeability.

The files provided include the necessary scripts to run the coastal permafrost model. To run the scripts, a FlexPDE license of version 7 or newer is necessary. Three folders are provided corresponding to three intrinsic permeability scenarios (k = 1?10-13; 1?10-14; 1?10-15). Within each folder are three initial condition files for concentration, head and temperature (i.e., initial_conc_k13.dat; initial_head_k13.dat; and initial_temp_k13.dat) corresponding to the intrinsic permeability scenario. Additionally, each folder includes four FlexPDE scripts which are distinguished by the scenarios that the script is capable of running. The scenarios are as follows:
1) Scenarios without warming or sea-level rise (SLR)
2) Scenarios with warming but without SLR
3) Scenarios without warming but with SLR
4) Scenarios with warming and SLR
For scenarios 2) & 4), the desired rate of land surface warming (Lw) and ocean warming (Ow) must be specified for the desired warming conditions. For scenarios 3) & 4), the magnitude of SLR is specified. The included simulations refer to warming associated with the RCP 2.6 emissions scenario. 
To change the rate of SLR, edit the SLR variable. 
To change the rate of land surface warming and ocean warming, edit the Lw variable and the Ow variable, respectively.
