The Sediment Transport (ST) module for QGIS and SMS(*) GUIs is an add-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, and interaction with the bed material keeping track of the evolution of bed fractions.  The RiverFlow2D ST model 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 riverbed changes for diverse scenarios.

What can you simulate with RiverFlow2D ST?

  • Two-dimensional erosion and deposition assessments rivers and estuaries

  • Determine general river degradation and erosion patterns due to reduced sediment inflow 

  • Evolution of riverbeds with a wide range of grain size distribution

  • Reservoir sedimentation and flushing

  • General sediment transport evaluations

  • Riverbed armoring
