| Abstract: | The analytical solution of the method of dimensionless transverse-cumu- lative discharge is usually derived in calculation of transverse spreading of a plu- me in steady nonuniform flows, but the method can not describe channel irregul- arities and the variation of discharge intensity in situation, and so on. This paper employs Stone-Brain implicit finite difference method and an example shows this method is feasible and excellent, Some problems on program design and computat- ion are also discussed. |
