Southern Willamette Valley Groundwater Management Area

Hydrogeologic Field Investigation and Groundwater Flow Model of the
Southern Willamette Valley, Oregon.

M.S. Thesis project of Jeremy Craner, OSU Geosciences

Jeremy constructed a 3-D computer
model of groundwater flow and contaminant transport within the GWMA and surrounding areas,
using a program called GMS-MODFLOW. This model should help us to
understand some of the issues to be addressed within the GWMA.

• Learn more about how the model works
• See the model's predictions in answer to three sample questions about groundwater flow in the Southern Willamette Valley.
  
  • How
    long does nitrate take to move from one point to another
    within the Valley?
    • Nitrate Travel Time Map
    • Implications
  • In what
    direction and how fast do we expect nitrate to travel in the
    Bottom Loop Road area of Coburg?
    • Coburg Travel Time Map
    • Implications
  • What are the
    effects of groundwater pumping on local groundwater and
    surface water?
