Employing artificial intelligence to predict δ18O and δ2H isotope ratios in precipitation in Iraq under changing climate patterns
This study employs machine learning to predict rainfall isotopic values in Iraq, crucial for water resource management and climate change. Using data from 32 meteorological stations over 14 years, including precipitation, temperature, humidity, and elevation, the Random Forest (RF) model demonstrated superior predictive performance (R² = 0.89, MAE = 1.39, RMSE = 3.5). The findings highlight the efficacy of AI-based models in reconstructing historical isotopic datasets, aiding climate variability assessment and sustainable water management in arid regions.

Stable Isotopes in Hydrology
Stable isotopes of hydrogen (δ2H) and oxygen (δ18O) act as natural tracers in the water cycle. Their ratios in precipitation are influenced by climatic factors like temperature, humidity, and elevation, providing insights into water origins, movement, and paleoclimatic conditions. They are crucial for understanding hydrological and climatological systems, especially in arid regions like Iraq.
Machine Learning for Prediction
Machine learning algorithms, such as Random Forest (RF), Support Vector Machine (SVM), Gradient Boosting (GBR), and Artificial Neural Networks (ANN), are powerful tools for building predictive models. In this study, these models are used to forecast δ18O and δ2H values based on meteorological parameters. RF showed superior performance due to its ability to handle non-linear relationships and robustness.
Data Augmentation Techniques
To improve model reliability and prevent overfitting, data augmentation was employed. This involved creating 100 new samples per original data row by introducing slight random changes (±10%) to input features like rain amount, temperature, and relative humidity. This expanded the dataset from 279 to over 27,600 samples, enhancing the model's ability to generalize to unseen data.

Impact on Water Resources Management in Arid Regions
The ability to reliably reconstruct rainfall isotope signatures from routine meteorological data offers a continuous, spatially and temporally rich source of isotope information, even when direct sampling is limited. This is particularly valuable for arid and semi-arid regions like Iraq, where water resources are scarce and highly sensitive to climate change.
Key Takeaway: This breakthrough allows policymakers and hydrologists to better assess water origin, track movement within ecosystems, and make informed decisions for sustainable water resource management and climate adaptation strategies.
