This paper probes into the morphological characteristics of the wide, straight, curved and branched connection reach between the straight relaxing and bending braided part of the Yangtze river, analyzes the influential factors on the channel of the connection reach based on the example of a typical river reach, and puts forward the channel management ideas for the connection reach, i.e. fencing the low beach of the braided reach, limiting the lateral change of the river, firming the bottomland form of the braided entrance area, and shaping the connection reach into a smooth one with reasonable curvature in the dry season.
