Itzï includes a surface flows model and a drainage network model. You can easily model culverts, inundations from drainage overflows etc.
Itzï is built on top of GRASS GIS. No need to crop or resample your source maps thanks the GRASS computational region. Get your final results faster with the GRASS tools for spatial and temporal analysis.
