The soil freeze-thaw model simulates the transport of heat in soil using a one-dimensional vertical column. The model uses a standard diffusion equation discretized using a fully-implicit scheme at the interior and a semi-implicit scheme at the top and bottom boundaries, similar to NOAH-MP. More details are provided below.
Detailed instructions on how to build and run the SoilFreezeThaw (SFT) model can be found in the INSTALL guide.
- Test examples highlights
- Unittest (see tests)
- Synthetic example (standalone mode): simulations with prescribed soil moisture profiles (static input) (see build/run)
- Real field example (pseudo framework mode): simulations with real forcing data (see build/run)
- Examples (nextgen framework mode):
- Synthetic example: Identical to the above
Synthetic examplebut runs in the nextgen framework. - Real field example: Identical to the above
Real field examplebut runs in the nextgen framework. - Real field example: Two nextgen realization examples coupling 1) SFT with CFE and 2) SFT with LASAM running on a catchment in HUC01 region are also provided in examples directory. Build and run instructions are given at build and run, respectively.
