Based on the existing achievement of research on the bank collapse occurred in the middle and lower reaches of the Yangtze River,this paper probes into the situation of previous studies from three perspectives:the morphological study,the dynamic process of water and sediment and the slope stability.Meanwhile,it points out scientific problems needing further research,and suggests that the relationship between the evolution of river regime,soil properties and morphology of bank collapse,complex flow in the bank collapse section,accumulation at the foot of bank,accumulation and decomposition of collapsed soil will be further directions in the bank collapse research.
