The Pollutant Transport (PL) module for QGIS GUI allows simulating the dispersion 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.

What can you simulate with RiverFlow2D PL?

  • Two-dimensional pollutant dispersion in rivers and estuaries

  • Determining the pollutant concentrations based on virtually any discharge scenario

  • Evaluate pollutant plume maps and evalution in time

Why choosing RiverFlow2D PL for pollutant transport assesments ?

  • Full two-dimensional equations on flexible meshes

  • Finite-volume numerical solution for exact mass, momentum and dispersion conservation

  • Import any terrain elevation data files

  • Automatic generation of flexible mesh that can be adapted to any geometry and complex terrain

  • Consider multiple pollutants simultaneously, e.g. salinity, e-coli, etc.

  • Evaluate multiple pollutants that interact with linear reaction rates

  • Provides faster runtimes than any other model using GPU technology and Cloud Computing

  • Output animations and high-quality maps 

  • Fully integrated with QGIS GUI

  • Online training and technical support
