In this paper a comprehensive study has been carried out about the frequency of floods in the major river systems of India during the summer monsoon season of 18-year period from 1986-2003. Frequency of floods in each river system have been worked out on the basis of total number of floods that occurred at different gauge/discharge (G/D) sites on these rivers. This study has shown that there is an increasing trend in floods of the Himalayan rivers which are the major tributaries of the Ganga river system thereby showing increasing trend of floods in the Ganga river system. Slight decreasing trend is noticed in the Brahmaputra river system. Peninsular rivers do not exhibit any noteworthy trend. Besides this, highest frequency of floods at each G/D site and a list of highest floods recorded at G/D sites which were 5 m and more above their respective danger levels during the last 50 years from 1954 have also been given in this study. This study has brought out the fact that Dibrugarh site in northeast India has recorded highest number of floods in 1990 and the highest floods of the order of 18 m above its danger level was recorded at Anderson Bridge site on the Teesta river in October 1968.
