In support of research interests and projects, I write software mainly in Java and R, and sometimes in Fortran and Python.  My open source software projects are on GitHub/bradleyjeck.

epanet2toolkit is a package for making water network simulations using Epanet in R.

epanetReader is a package for reading water network files in Epanet‘s .inp and .rpt formats into R.

Perfcode  is numerical model (in Fortran 90) for simulating drainage from roadways, especially those paved with porous asphalt.
