Implication

This analysis compares multiple machine learning methods for predicting flood risk, indicating the effectiveness of tree-based models.

Key Points

  • XGBoost achieved the highest Area Under the Curve (AUC) of 0.87, demonstrating its superior predictive ability in flood risk mapping.
  • Multiple machine learning algorithms were applied in flood risk assessment, highlighting the importance of using advanced ML techniques.
  • Environmental parameters such as Digital Elevation Model and Topographic Wetness Index were crucial for accurate flood susceptibility modeling.
  • The findings emphasize the effectiveness of ensemble methods, especially in complex environmental contexts like northern Iran.
