Abstract/Description: | Regional evaluation of drought characteristics provides useful information for sustainable water resources management. In the present study, the Standardized Precipitation Index (SPI) was applied to investigate the meteorological drought in the Parambikulam-Aliyar basin, Tamil Nadu. The basin monthly rainfall data for the period 1972–2012 were used for spatial interpolation of rainfall using the GIS techniques. Firstly temporal variation of drought was assessed using the regional representative SPI values at multiple time scales calculated from mean areal precipitation. Then, drought severity was assessed, and the spatial variation of drought severity was analyzed for identifying the most affected areas for a specific drought event. The analysis of the SPI suggests that the basin had suffered severe and extreme drought in the 1970s and 1980s. Drought severity maps indicated that the annual average drought severity and most intensive quantity were high in the central and northern parts of the basin. The results of this study can be used for developing drought preparedness plan and mitigation strategies within the basin. |
