Implementation of Rainfall-Based Drought Indices for Regional Drought Assessment
Regional drought monitoring is a vital constituent of drought risk management. The effects of drought on the environment and ecosystem may cause disasters and result in socio-economic problems. Drought indices are an extremely useful tool for regional drought assessment. In this study, various rainfall-based drought indices are used for drought assessment of its four districts of the state of Odisha India. The six indices Standardized Precipitation” Index (SPI), Percent of Normal Index (PN), China-Z index (CZI), modified CZI (MCZI), Z- Score Index (ZSI), and deciles index (DI)”differ in their exposure and classification of drought procedures in the study area. Further, a comparative analysis has been done among all the rainfall-based indices. The differences mention among the drought indices in noticing drought in the events in the study area can be reduced by using numerous drought indices in computation to the use of SPI, in drought taxations. It is observed that SPI captured the historical extreme and severe drought periods successfully, and can be suggested to be applied to this district as drought assessment tools.
