Welcome to TRITON
The Two-dimensional Runoff Inundation Toolkit for Operational Needs (TRITON) is an open-source, computationally efficient two-dimensional flood modeling toolkit that scales from a laptop to supercomputers. It solves the full shallow-water equations on CPUs and GPUs to produce fast, reproducible flood-inundation maps.
