2003 NSF REU Soil Evaporation and Classification Kacey Cubine, Scott Horton, Rose Rotter, and Noah Friesen
Featuring • Brief Overview • Project Objectives • Procedure • Results • Conclusions • Continuing Research
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.
The Debates • Drought • Current Events • Restoration Projects
Objectives • To locate appropriate sites for field research • To classify the soils at those locations • To infer soil evaporation behavior from soil conditions
Sites Middle Rio Grande Valley
Classification Tests • Sieve tests • Hydrometer • Atterberg limits
Soil Properties • In situ Density • Specific Gravity • Hydraulic Conductivity • Suction • Moisture Characteristic Curve
Results Shirk Data Sevilleta
Conclusions ==Location== • Sites were found, but are not perfect. • Water table depths between 122 cm and 162 cm.
Conclusions • Layers are not consistent throughout the Bosque. • Predominant soil types. ==Characterization==
Conclusions • There is a potential gradient. • Equipment is not perfect. • Time is of the essence. ==Tensiometers==
