What They Do

CFD
(FLUENT, FLOW-3DTM)
Simulating complex two- and three-dimensional flow with no slip boundaries
  • Solve the Reynolds-Averaged Navier Stokes Equations
Riverine
One-Dimensional
(MIKE11, HEC-6,
and HEC-6T)
Predicting long-term adjustments in channel profile due to erosion and sedimentation
  • Compute laterally varying but depth-averaged flow
  • Provide understanding of where sediment deposition will occur
  • Give information about the local flow patterns where fluid properties are uniform
Riverine and Coastal
Two-Dimensional
(MIKE21, MIKE21C,
and RMA-2, SED-2D)
Computing laterally varying but depth-averaged flow Where fluid properties are uniform:
  • Provide understanding of where sediment deposition will occur
  • Give information about the local flow patterns
Riverine and Coastal
Three-Dimensional
(MIKE3, CH3D-SED,
 and FLOW-3DTM)
Problem solving for applications where two-dimensional models are unable to capture important aspect of the problem physics
  • Identify stratified flow due to thermal and or salinity
    gradients or river diversions where the diversion has a significantly different depth than the main channel
