Abstract: Tensiometers installed with a ground surface or other reference can be used to determine ground-water equipotentials and the position of the water table in the field. Tensiometer determined water tables were roughly comparable to those measured with perforated wells in a sprinkler irrigated Coachella fine sandy soil. Water differences depended on the flow conditions and proximity of the tensiometers to a drain. Shallow ground-water equipotentials can be determined above and below the water table with a tensiometer system.
