| Abstract | This research aimed to analyze the severity level of drought by using the Standardized Precipitation Index (SPI) in the Eastern Economic Corridor (EEC). The six meteorological stations, Bangkok Metropolis, Chanthaburi, Chonburi/Sattahip, Koh Sichang, Pattaya, and Khao Ito, over 30 years data from 1988 to 2017, were used in this research. The three patterns of moving cumulative rainfall of 3, 6, and 12 months were used to estimate the indices of SPI3, SPI6, and SPI12, respectively. As a result, the averaged values of 3 patterns of SPI ranged from 0.035 to 0.180, which was interpreted as a level of near normal. The maximum and minimum values of the SPI could experience drought conditions in both severe to extreme drought and wet. However, the results demonstrated that more than 62 % of the SPI ranged near normal. The value of SPIs approximated moderate to extreme droughts below 17 %. The results of this research could be a part of the information to support water management in the study area to develop a suitable plan to mitigate the effect of drought in the future. |
