This paper presents the results of some of the Jamuna River erosional hazards from Bahadurabad Ghat to Bhuapur (near JamunaBridge). Results are also presented on the Jamuna River accretion and water discharge. Landsat images from 1977 to 2014 and waterdischarge data were analysed to find out a relationship between dynamics of erosion and accretion for different time intervals withaverage annual water discharge. It is clearly established that total amount of erosion and accretion rates varies with different times.The highest erosion rate 21.15 km2 year-1 was observed in the period of 1989-1992 and the highest accretion rate 13.57 km2 year-1was observed in the period of 1980-1989. The erosion and accretion values fluctuated with increasing average annual maximumwater discharge but the difference between erosion and accretion had remained low before water discharge reached to 67000 m3s-1and it is estimated higher after crossing annual average maximum water discharge of 67000 m3s-1. This discharge value also playsan important role on bar development and active channel. It is also observed that unvegetated bar areas remained higher than activechannel areas before average annual maximum water discharge reached to 67000 m3s-1. Finally, all the erosional hazards andaccretion values are compared and evaluated to see their influence on the annual discharge
