Unsaturated Soil Water Flow Model
PyWaterBal is a unsaturated soil water flow model. It models the vertical flow (one-dimensional) of water in the soil, following a "tipping bucket" system. This model was published as a book by Uni. Putra Malaysia Press (also see references below).

At the command prompt:
python pywaterbal.py <flags>
where <flags> are the following:
-i <model input text file>
-o <model output/results text file>
-n <number of daily time steps to run the model, in days>
-p <plot charts to show the model results, optional>
The -p flag is optional and must either be b for basic chart plotting. For detailed chart plotting, use any single letter other than b.
Example:
python pywaterbal -i 'c:\pywaterbal\ini.txt'
-o 'c:\pywaterbal\out.txt'
-n 90
-pb or -pd
means the model input is ini.txt and output file is out.txt, and both these files are stored in c:\pywaterbal\ folder. The model is to be run for 90 simulation days, and after the model run, the simulation results will be plotted. The 'basic' chart plots will be produced if -pb is specified, else -pd for more detailed charts.
