These optional plug-in modules expand the RiverFlow2D capabilities for mud/debris flows and tailings dam flooding, erosion and deposition studies, and pollutant dispersion assesments
RiverFlow2D MD: Mud & Debris Flow Module
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.
RiverFlow2D ST: Sediment Transport Module
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 asses 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.
RiverFlow2D PL: Pollutant Transport Module
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.
