Abstract
Microlysimeters of different sizes( 5 cm 10 cm and 15 cm in length) were used extensively in the present study for the measurements of soil evaporation in situ in an extremely arid area in southern Israel. All of the data obtained from the microlysimeters were used to evaluate two conventional evaporation models developed by Black et al. and Ritchie, respectively. Our results indicated that the models could overestimate total cumulative evaporation by about 30% hi the extremely arid environment. Reducing the power factor of the conventional model by a factor of 0.1 produced good agreement between the measured and simulated cumulative evaporation. Microlysimeter method proved to be a simple and accurate approach for the evaluation of soil evaporation.
