18. Results

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

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
