NEW! Modeling Oil Spills

OilFlow2D the new member of Hydronia suite of models. This unique software is able to simulate oil spills over land and a forthcoming update later this year will allow modeling spills on water. Ask us for an online demonstration session at

The model offers the fastest and most advanced finite-volume viscous flow free-surface 2D engine based on unstructured flexible meshes to handle oil flow over complex terrain. >> More information.

A breakthrough in 2D hydraulic modeling!

RiverFlow2D Plus is a powerful two-dimensional river and estuary flexible mesh models that can tackle the most demanding flood modeling situations including dam-break and levee-break simulations. Its stable and fast finite-volume engine allows treating high speed flows and fast frontal waves over initially dry terrain. >>More information.


Three new RiverFlow2D Plus modules expand the model capabilities even further: Mud & Debris Flow, Sediment Transport and Pollutant Transport.

Speed up! The next level of 2D hydraulic modeling.

RiverFlow2D Plus GPU is our new two-dimensional model that achieves simulation speeds never seen before allowing solving large river hydraulic problems that used to be impractical or even impossible until recently.


The release of the GPU version of RiverFlow2D Plus flexible mesh model is already creating a splash in many flood and river modeling applications, running up to 100 times faster than non-parallelized or CPU parallelized models. >> More information.
