  • The study identified 2001 as a wet year and 2009 as a dry year within the 2000-2012 period. In 2001, the northern part of the region showed Standardized Precipitation Evapotranspiration Index (SPEI) values between 1.5 and 1.99, while other areas had values below 1.5. During the dry period, SPEI values ranged from -1.0 to -1.49 in the North and were lower than -1.5 in the South.
  • The research utilized GIS to interpolate data from 98 stations using the Standardized Precipitation Evapotranspiration Index (SPEI) at a 1-month scale. The Spline interpolation method was determined to be the optimal approach for the region based on the correlation between interpolated data and the normal distribution of precipitation.
