It is still a common practice to infer field values of soil water content (or of soil water suction) from the measurement of the soil water suction (or the soil water content) and the use of “representative”soil water characteristics. A series of independent measurements of changes in water content and in soil suction were conducted on two watersheds during 1 year. It is clearly shown on both sites that hysteresis is too important to be neglected, and that considerable errors will result from the determination of both water content and soil suction with the use of a single sensor.
