Simstrat is a one-dimensional physical lake model for the simulation of stratification and mixing in deep stratified lakes. The model was originally developed by Goudsmit et al. (2002) and has been successfully applied to lakes with different physical properties. For a few examples, see the key publications below.
Simstrat has also been applied to a range of lakes in Switzerland. The results are regularly updated, and simulated temperatures for the current year are compared to long-term means.
The Simstrat code is freely available on Github .
Main properties of the Simstrat Model
- 1-dimensional physical lake model (resolving the vertical dimension)
- simulates temperature, salinity, stratification and ice cover in lakes and reservoirs
- k-ε model for turbulent mixing
- includes energy transfer to mixing via internal seiches
- inflows can be added at specified depths or with density-dependent intrusions
- variable lake levels
- programmed in object-oriented Fortran 2003
- parameter estimation using PEST is implemented
