Polynomial regression to forecast earth dam piezometer levels gives a quadratic expression of the piezometer data variation versus reservoir level, which indicates a hysteresis of the piezometer measurements at mid-reservoir levels for increasing reservoir levels compared to decreasing reservoir levels. Forecasting of the piezometer levels based on the calculated quadratic expressions gives expected piezometer values with mean square error around 10% of the standard deviation of the polynomial regression curves.
