##### 758 Studying the Spatial Variations of Stable Isotopes (18O and 2H) in Precipitation and Groundwater Resources in Zagros Region

**Authors:**
Mojtaba Heydarizad

**Abstract:**

^{18}O content of precipitation and groundwater resources showed spatial variations across Zagros region as southern parts of Zagros region showed more enriched isotope values compared to the northern parts. This is normal as southern Zagros region is much drier with higher air temperature and evaporation compared to northern parts. In addition, the spatial variations of stable isotope δ

^{18}O in precipitation in Zagros region have been simulated by the models which consider the altitude and latitude variations as input to simulate δ

^{18}O in precipitation.

groundwater,
precipitation,
simulation,
stable isotopes,
Zagros region
