**2.3 Oasis evapotranspiration (ETo)**

Oasis ET is the amount of water consumed by a small irrigated vegetation which is encircled by a widespread dry-area, at which dynamism of water to vapor is come from high temperature in combination with drought [16, 18]. **Figure 2** shows the border area necessary for minimizing the lateral transport of energy from the dry to the wet area (irrigated). At such an area, the ET that will take place is the oasis ET.
