RiverFlow2D SWMM: SWMM Storm Drain Network Module is now available! 

Hydronia LLC is a water resources engineering consulting firm specialized in advanced numerical model applications to simulate river flows, oil spills, sediment and pollutant transport. 

Our firm develops and distributes RiverFlow2D and OilFlow2D numerical models and may assist you in any hydraulic engineering project offering accurate and fast solutions from our highly qualified and experienced professional team.  


SWMM Storm Drain Network module integrates all the capabilities of the EPA-SWMM Storm Drain model with RiverFlow2D model. This allows performing simulations of urban flooding with full and dynamic interaction of the surface runoff with the storm drain network routing.

RiverFlow2D for QGIS provides all the tools necessary for generating the flexible mesh, integrating the RiverFlow2D components such as bridges, weirs, gates, culverts, Dam breach, etc., creating professional maps of 2D model results, building animations, all within the QGIS environment.

RiverFlow2D Flood Simulation for Autodesk  InfraWorks: a collaborative effort between Autodesk and Hydronia. It is a limited technology that matches the simplicity of two-dimensional (2D) flood simulations together with an immersive 3D model.

RiverFlow2D for Tailings Dam Break Risk Assessments: offers unique tools to evaluate flood risk originating from sudden dam and tailings dam breaks. Selecting one out of 8 non-Newtonian rheological laws, the model can consider virtually all possible tailings ranging from relatively low-density high-water content fluids to granular materials.
