That shows the branchriver deposition is affected by the main river deposition. In flood season, mud flow come upward in branchriver and make sedimentation.
The relaxation iterative method for solving branchriver networks is extended, which can turn the problem of any complex river networks into the problem of a series of single rivers.
With the measured data of main and branchriver in reservoir region of XLD project, the deposition feature in branch rivers and its relation with the main river deposition are researched.
