Abstract
A transient dispersion-convection equation, which appears in the problems of heat and mass transport in flowing groundwater, is solved numerically by means of a finite element method coupled with the method of characteristics. Numerical errors such as numerical dispersion and oscillation, generally encountered in solving dispersion-convection equations numerically, can be eliminated by using the proposed method. Numerical solutions by the characteristic finite element method showed good agreement with analy-
