ASSESSMENT AND MAPPING OF METEOROLOGICAL DROUGHT USING STANDARDISED PRECIPITATION INDEX FOR SOUTHERN DISTRICT OF TAMILNADU
ArcGIS 10.3, Indian Meteorological Department (IMD), Microsoft Excel, Standardized Precipitation Index (SPI)
Among the different natural hazards, drought is one of the most disastrous as it inflicts untold numerous miseries on the human societies. Drought is a long time period of dry weather, when an area gets less than its normal amount of rain, over months or even years. Crops and other plants need water to grow, and animals need water to live. Some factors driving the climatic changes such as temperature, pressure, rainfall, humidity, sea surface temperature etc. Two third of India has low precipitation which means that the precipitation rate is less than 1000mm. As per Indian Meteorological Department (IMD), Tamilnadu has Mild and moderate drought conditions. In this project, the station wise rainfall data, Landsat 7 and Landsat 8 satellite images were used for drought assessment from 2004 to 2019 with five years interval. Study area of this project was Sothern districts of Tamilnadu such as Kanyakumari, Tirunelveli, Tenkasi, Thoothukudi, Virudhunagar, Ramanathapuram, Madurai, Sivaganga, Pudukkottai and Dindigul. In that, the Standardized Precipitation Index (SPI) values are used to identify the meteorological drought SPI was calculated through Microsoft excel software and mapping was done by ArcGIS 10.3 software. As a result, 2019 is considered as a drought year compared with 2004, 2009 and 2014.
