Abstract :
An attempt has been made to study the variability of seasonal and annual rainfall for a period of 25 years (1991-2015) for the upper Cauvery portion which has five districts. It can be observed that the average annual rainfall for every five years considered range from 800 to 1200mm for more than 45 percent of the area upto 2010 and from 2011-2015 it has been reduced to less than 35 percent and the percentage of area for which the rainfall range was less than 800mm was increased to 28.39 percent which was less than 14 percent from 1991-2010. The maximum portion of the area had average post monsoon rainfall between 100mm to 200mm has been from 1991 to 2010. And from 2011-2016 the maximum portion of the area has a average post monsoon rainfall less than 150mm. Some parts of Hassan, kodagu and chikkamangalore districts portions in the study area has average annual rainfall above 2000mm where as mandya district portion in the study area has annual rainfall less than 800mm and in mysore district average annual rainfall ranges from 800mm to 1500mm
