Estimation and Analysis of Seasonal Rainfall Distribution and Potential of Türkiye and Its 25 Main Watersheds

In this study, the seasonal rainfall distribution in Türkiye and its 25 main watersheds were estimated, potentials calculated analyzed. Empirical Bayesian kriging (EBK) ordinary (OK) methods applied interpolations. The calculations made through EBK, which provided highest estimation accuracy all seasons. winter, is season with rainfall, Türkiye’s depth 208.8 mm, volume 162.87 billion m3. summer, lowest 61.7 48.13 are Antalya (480.1 mm) Ceyhan (222.8 spring, East Black Sea summer (197.5 autumn (299.7 mm). Conversely, precipitation Aras (74.9 Little Meander (16.5 Konya spring (131.3 (86.2 shortage observed Central Southern parts of Türkiye. As we go from north to south, watersheds’ depths shares become more irregular variable.
