Abstract: Tam Xa bank of Red River is a curved segment of the river flowing deep on the large bank, the high flow velocity in flood season rushing and pressing close to the bank is the main cause of riverbank damage. Based on the analysis of real data measured and studied the hydraulic section of the river section on the physical model, the author has shown the essential nature and causes of river bank erosion in this section due to the interaction. between the river shape, the movement of the middle beach and the flow causes erosion and changes the river bed. Deep creeks and dynamic shafts close to the river banks with relatively close distance at the water level. Large coastal velocity, in the area of landslide from 1.0 ÷ 1.5 m/s corresponding to creating water level, locally has a place larger than 2m / s and tends to push to the left bank. On the other hand, due to the characteristics of Tam Xa beach, which are quite large over 3km, when floods rise and floods recede with a large flow, the spillway velocity is also the impact on river banks.
