The rate of evaporation on the study area is very high, actually more water evaporates than the amount of precipitation. Despite of this high rate of evaporation the effect of
evaporation on the stable isotopic composition of the shallow groundwater is small. The reason is most probably that this area is a regional discharge area, the rate of infiltration of precipitation
is low, and mixing between ascending old groundwater and infiltrating modern water is driven by diffusion. The other argument for this low isotopic effect of evaporation is that in this kind of
soil (clay loam Solonetz soil) below 40-50 cm the evaporation of groundwater takes place at no isotopic fractionation (Allison et al. 1984; Gazis & Feng 2004), water moves upward mostly by capillary effect.
