| Abstract: | A numerical method for coupled solution of the equations of groundwater flow and pollution transportation is presented on the basis of operator-splitting algorithm, and the application of Kalman filtering technique into the study of groundwater pollution are explored also in the present paper. Computative examples indlicate that the numerical method and application of Kalman theory can avoid the unhealthy tendencies in numerical modeling and hence attain the computative accuracy considerably. |
