| Abstract: | In this paper, a non-Uniform, mixed type model for predicting the water quality of the Lakes in arid desert basins areas is presented. The law of variation describing the movement, distribution and concentration of pollution in the lake is controlled by a group of equations,with corresponding boundary conditions numerical computation and verification are made for the concentration field of mineralization and the result coincides with the data of observation, therefore,the program can be the mathematical model for predicting the water quality of the lakes in arid desert basins areas. |
| Keywords: | flow field concentration field mineralization alternative divection implicit method (A D I M) |
