Abstract

The Standard Precipitation Index (SPI) is employed to predict, track the upcoming, recurring drought intensity and magnitude. The standard precipitation index has several characteristics that are an improvement over previous indices, including its simplicity and temporal flexibility, that allow its application for water resources an all times cables. In this work regarding analysis of drought severity of Dharwad District, Karnataka by taking 30years of rainfall data .By use of standard precipitation index finding the future drought prone area in and most rainfall receiving are in that district. As Dharwad contains very few rivers and water bodies the water source is majorly dependent on rainfall, hence this study places an important role in predicting and getting of upcoming drought in Dharwad district.

Highlights

The standard precipitation index is a widely used index to characterized meteorological drought on a range of time span
The Standard Precipitation Index (SPI) can be compared across regions with markedly different climates over the years many drought indices world developed and used by methodologists and climetoglist around the world
This ranged from simple indices such as percentage of normal precipitation and precipitation percentiles to more complicated indices such as Palmer drought severity index
