|Abstract:||Water an important source for human beings. The major source of water is the rainfall which is the key factor in determining the sustainability and conservation of living organisms on the earth. Around 80 % of the rainfall occurs during monsoon seasons which results in floods and sometimes results in drought due to the seasonal variations. Hence, it is necessary to analyze the rainfall during the seasonal period. The present study deals with the characteristics of rainfall of the northern part of Erode District. The rainfall data for the period of 20 years (1993-2012) were collected with a mean monthly rainfall data of the five rain gauge stations located in the study area, analyzed and categorized as four different seasons. These rainfall data were used to obtain the rainfall pattern by Geographical information system (GIS) and the spatial distribution maps for all the four seasons were prepared by Inverse Distance Method in ArcGIS. The study shows that the area covers under high rainfall is 51.74 km2, 1332.24 km2 and 1492.13 km2 during pre-monsoon season, South west monsoon and North East monsoon and during post-monsoon the low intensity of rainfall were observed which covers around 1492.13 km2 of the study area.|
