This paper aims to examine the nature of flood character in different parts of the basin taking some relevant flood parameters like flood frequency, flood affected area, flood statgnation period, flood level height. Inference has drawn regarding flood intensity zones based on major flood years since 1978 to 2011. It is found that flood 2000 was the most devastating flood after that flood intensity and affected areas have declined. Out of total basin 21% land is highly affected by flood and it is mainly concentrated in the depressed wetland tract in the lower part of the basin.
