  1. 2003 NSF REU Soil Evaporation and Classification Kacey Cubine, Scott Horton, Rose Rotter, and Noah Friesen

  2. Featuring • Brief Overview • Project Objectives • Procedure • Results • Conclusions • Continuing Research

  3. From Birth to Extinction • Over 1,800 miles in length • Draws water from Southern Colorado Rockies • Water used for irrigation, residential, tribal, recreation, and habitat.

  4. The Debates • Drought • Current Events • Restoration Projects

  5. Salt Cedar Removal

  6. The Salt Cedar

  7. Objectives • To locate appropriate sites for field research • To classify the soils at those locations • To infer soil evaporation behavior from soil conditions

  8. Sites Middle Rio Grande Valley

  9. Shirk

  10. Belen

  11. Sevilleta

  12. Bosque DelApache - North

  13. Bosque Del Apache - South

  14. Classification Tests • Sieve tests • Hydrometer • Atterberg limits

  15. Soil Properties • In situ Density • Specific Gravity • Hydraulic Conductivity • Suction • Moisture Characteristic Curve

  16. Tensiometers

  17. Results Shirk Data Sevilleta

  18. Results

  19. Conclusions ==Location== • Sites were found, but are not perfect. • Water table depths between 122 cm and 162 cm.

  20. Conclusions • Layers are not consistent throughout the Bosque. • Predominant soil types. ==Characterization==

  21. Conclusions • There is a potential gradient. • Equipment is not perfect. • Time is of the essence. ==Tensiometers==

  22. Future Research
