Abstract: In this paper, a nonlinear partial differential equation governing a change of shoreline is derived, its solution is expanded as an asymptotic series in a small parameter. Then the Green function is obtained by means of Fourier transform and the solution is expressed using the Green function. The results obtained show that Delta growth is asymmetrical due to sand input from river and longshore current, It tries to explain asymmetrical growth of the Delta of the Changjiang River.

Key words: local non-similarity, suction/injection, buoyancy force, magnetic field, wall of wedge
