Delta Hydro Studio
Browser-based hydrology and hydraulics calculators for practising engineers — no install, report-ready output.
Run and read EPA SWMM from R — model execution, results import and GIS conversion on CRAN.
Install
install.packages("swmmr")swmmr connects R to the SWMM engine: execute simulations, read the binary output into tidy data structures, convert models to GIS formats and build simple optimisation loops around the engine. For teams whose analytics live in R rather than Python, it covers the same ground PySWMM/swmmio cover — run, read, iterate.
Development has slowed, but the package is on CRAN, documented, and the SWMM file formats it targets are stable, so it remains perfectly serviceable for scripted SWMM work in R.
