SIAM Application to Yakima Basin

• HEC-RAS Model will provide hydraulics

• Bed material sampling will specify the composition of the channel and sediment transport parameters

• Each hydrologic regime will represent a different SIAM scenario

• Data Products Include

  • Evaluate Channel Stability
  • Determine Source and Sink Reaches
  • Evaluate Fining or Coarsening of the Bed
  • Identify potential areas requiring mitigation

• The SIAM model may identify reaches which could benefit from a more detailed mobile boundary model.
