This One-Dimensionized Solution (1-DS) suggests that multi-dimensional characteristic differential equations be split up on its space directions, perpendicularly one to the other. Any one is considered as a constant lateral flow of the other. The 1-DS need not solve the equations set but use interpolations. There are three interpolations used: explicit form of distance, explicit forms of time, and the implicit hybrid form of distance and time. The last one has promoted the 1-DS to a better status. It has been used on the seashore reclamation computation of Pearl River mouth. And the upstream boundary condition Q-t curve is assumed to be constant.
