RiverFlow2D Modules

It is a comprehensive computer model used to simulate a wide range of hyperconcentrated flows ranging from non-Newtonian mud and debris flows to movement of granular materials. It is also useful to simulate inundation from sudden failure of tailings dams. The module has been thoroughly tested with real data and in projects worldwide. The numerical engine uses the same high accurate finite-volume method of the RiverFlow2D model making it the most advanced mud/debris flow flexible mesh two-dimensional model. RiverFlow2D MD offers eight different friction formulas for non-Newtonian and granular fluids for realistic predictions of runout distances in complex terrains. >> More

The Sediment Transport Module is a ad-on software that complements RiverFlow2D hydrodynamic computations with capabilities to simulate erosion and deposition in rivers and estuaries. The ST module includes formulations that consider transport of fine sediment in suspension, coarser sediment using bed load approach, and combined suspended and bed load transport. It provides options to use multiple sediment size fractions.  The RiverFlow2D model with the ST module is the right combination to assess impact of designs to control erosion in rivers, river reach geomorphologic analyses for restoration assessments and evaluating the evolution of the river bed changes for diverse scenarios. >> More

The SWMM Urban Drainage Network module integrates all the capabilities of the EPA-SWMM* Strom 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. You can integrate existing pipe network  SWMM 5.1 projects with RiverFlow2D meshes developed to simulate rainfall, infiltration, flow along streets, considering weirs, gates, and other urban structures. The flow exchange can be in both directions including manhole overflows that bring inflow onto the surface water mesh, and inflow from the surface into the storm drain network. >> More

The Pollutant Transport module allows simulating the movement of contaminants in water. It is fully coupled with the RiverFlow2D hydrodynamics calculations and considers solute transport by advection, dispersion and reaction. The PL module relies on the depth and velocities calculated by RiverFlow2D and computes solute concentrations at each time step for all cells.  The module can consider multiple reactive contaminants that can exchange mass with one another based on first order reaction terms. >> More 

The new RiverFlow2D PT plastic and particle transport module simulates the trajectory of plastics in water bodies. The PT module can be useful to understand, among other things, how current patterns affect the path of plastics or debris, and what are the potential areas of accumulation.
