DigiBog peatland development model code used in the paper 'Simulating the long‐term impacts of drainage and restoration on the ecohydrology of peatlands' https://doi.org/10.1002/2016WR019898. The model was used to simulate the growth and subsequent drainage of a sloping peat transect.
DigiBog was originated by Prof. Andy Baird, Prof. Lisa Belyea, and Dr. Paul Morris. The model was further developed for the work reported in the above paper by Dylan Young.
This version of the model runs in 2.5-D and comprises two files written in Fortran 90. They are; DigiBog_WRR2017_main.f90 and DigiBog_WRR2017_hydro_module.f90. A drain is not simulated in the main model code included here, but can be added to an active column by changing its status to a Dirichlet boundary condition at some point in the model run, and then fixing a water-table position to the required drain depth. The damming of the drain can be simulated by raising the water-table in the drained column.
The model uses five input files which are also included with the model code;
- User-defined input parameters - 010_DigiBog_BB_IN_information.txt
- Net rainfall time series* - 020_DigiBog_BB_IN_net_rain.txt
- Temperature time series* - 030_DigiBog_BB_IN_temp.txt
- Column status (active, boundary column, or inactive) - 040_DigiBog_BB_IN_column_status.txt
- Base altitude for peat columns - 050_DigiBog_BB_IN_baltitude.txt
*Note these net rainfall and temperature time series files have been randomly generated and are not the same files that were used in the publication. In this version of the model, the mean annual temperature is used for the plant litter productivity function and must be added to the user-defined input file (010_DigiBog_BB_IN_information.txt).
