Abstract
Groundwater is a valuable resource in the arid environments. Evapotranspiration (ETG) is the major component of the groundwater balance in these regions. In this study, the Loheide-method was used to estimate hourly ETG using the diurnal water table fluctuations and the variation ETG of throughout the day was analyzed. The methods mentioned above were applied to a pre-existing data set that was collected in a well (SB1) that is screened across the water table in the Subei Lake watershed in NW China. It is obvious that the pattern of estimated ETG and air temperature and solar radiation are very similar. The distinct feature of estimated ETG is the diurnal fluctuations. The results present a wide range of diurnal ET values ranging from 10 to 22 mm/d.
