Abstract
Kerala, one of the smallest States of South India, is blessed with forty-four rivers. River Pampa is the third largest river in the State of Kerala, 176km long with a catchment area of 2235Sq. km. Recurring tropical monsoon floods during every season, causing substantial damages, is one of the perennial problems experienced in this river basin. Studying rainfall trend in the river basin and its underlying features are vital in understanding the flood phenomena and its socio-economic impacts. The present study evaluates the trend of rainfall in the Pampa river basin, utilizing the data from five gauging stations. The time series of monthly and annual rainfalls for the past twenty two years have been analyzed statistically. Significant changes have been observed in the basin rainfall features - both seasonal and annual rainfall.
