DROUGHT INDICES MONITORING USING SPI AND Z INDEX SCORE FOR GUA MUSANG, KELANTAN - 1ST INTERNATIONAL CONFERENCE ON SCIENCE, ENGINEERING & TECHNOLOGY (ICSET) 2020
Drought has become prevalent in Malaysia due to exceptional rainfall deficit which in turn exacerbate the existing local water crisis. This paper is intended to determine the drought index in Gua Musang as one part of contribution to the development of drought index for the whole of Malaysia using the Standardized Precipitation Index (SPI) and Z score Index (ZI). The data collection used the rainfall data according to the identified station starting 2003- 2015 based on the completeness of the data. The results indicated that the SPI and ZI gave quite similar result in term of condition of drought event and depicted the strong correlation between SPI and ZI. Findings from this study is believed benefit water engineers by providing information a probability distribution of water scarcity under different drought condition thus the mitigation strategy can be taken in order to address the impacts especially on water supply.
