R-SWAT

1–30 of 152

This is an interactive web-based app (written in R language with shiny package) for parallel parameter sensitivity, calibration, and uncertainty analysis with the Soil and Water Assessment Tool (SWAT, this app was listed in SWAT website).

Link to google group for discussion: https://groups.google.com/g/R-SWAT

If you would like to contribute to the development of this app, please lets me know. Together we can make this app much better as my time for this app and R knowledge is very limited.
Whenever you use this app (again), just go the my GitHub repository and download the newest version (master branch).
