This study evaluates the consistency between three precipitation-based drought indices—the Standardized Precipitation Index (SPI), Percent of Normal Index (PNI), and Deciles Drought Index (DDI)—in the Asi Basin, Türkiye. Using 32–52 years of precipitation data from 11 stations, drought conditions were analyzed at monthly, seasonal, and annual scales. To ensure statistical robustness, Mann–Kendall trend tests were applied, and...

This study aimed to investigate the performance of machine learning (ML) algorithms in determining horizontal velocity at specific points using the current Global Navigation Satellite System (GNSS) velocity field. To achieve this objective, the analysis utilized the most comprehensive velocity field available for Turkey, where 70% of the GNSS velocities was allocated for training the ML algorithms, while the remaining 30% was...
