Abstract

A prototype size lysimeter was studied in the laboratory to determine accuracy and sources of error that might be caused by variable pillow contact area, temperature changes in various components of the indicating mechanism, and rate of lysimeter loading. The effect of degree of inflation of the hydraulic pillows on bearing plate contact area was examined in detail and found to have a significant effect on lysimeter calibration. Hysteresis in the indicating mechanism was not significant. The effects of rapid or gradual changes in lysimeter tank mass are not found to significantly affect lysimeter response.
