摘要:用分裂法将地下水溶质运移方程分成对流方程和弥散方程，对流方程采用熵格式求解，弥散方程采用中心格式求解.数值试验表明，该格式不会产生过量问题，没有出现非物理振荡，数值弥散较小.



Abstract:The equation of solute transport in groundwater is divided into the convection equation and the diffusion equation by using the splitting method. The entropy scheme is applied to solve the conservation equation while the central difference scheme is applied to solve the diffusion equation. Numerical experiments show that the scheme does not produce excessive problems, and no physical oscillation occurs.
