RiverFlow2D is the most advanced two-dimensional combined hydraulic and hydrologic flexible-mesh model, offering a high performance finite-volume engine for speedy, accurate, and volume conservative computations in all river and estuary projects. It can tackle the most demanding flood modeling situations including dam-break and levee-break simulations over initially dry terrain.
RiverFlow2D can be readily extended with Add-on Modules: Sediment Transport (ST), Mud and Debris Flow (MD), Pollutant Transport (PL) and Urban Drainage (UD).
RiverFlow2D can be run using two Graphical User Interfaces (GUI): QGIS or Aquaveo SMS. Both allow to generate the files needed to run the model.
RiverFlow2D GPU turns days-long simulations into hours-long runs and these into runs that require just a few minutes. This version can run 200 times faster than other flexible mesh models taking advantage of NVIDIA GPU Graphic Cards.
