Popis:	A numerical model is one of the useful measures to predict the characteristics of the environmental systems on the interface of different density water. In the last few years, some models were already proposed to calculate each problems like flow in the stratified closed water systems and the saltwedge, and realized beneficial results. However, these models also have some defects. For example, turbulent models are sometimes difficult to use actually because of its theoreticalcomplexity, and simple two-dimensional models can not calculate so accurately. So in this paper, the new two-dimensional numerical model is proposed, which use CIP-scheme in the calculation of advection phase, in order to calculate density flow more accurately without using complicated models, and its availability is confirmed by the comparison between the results of the calculation and that of the experiment under the same condition.
