Water Supply Project

• Need to provide input for Ecosystems Diagnostic and Treatment (EDT)

• Hydraulic Modeling (1-D and 2-D)

  • 1-D hydraulic model (Upper Columbia Area Office) for coarse evaluation of hydraulic conditions (wetted width, cross section velocities, etc.)
  • 2-D hydraulic model determines habitat quantity and quality on a finer scale for a few selected reaches (4 – 12 miles)

• Determine sediment transport conditions using SIAM

  • Provide input to EDT
  • Gain an understanding of potential channel change following increased flow
