| Abstract: | An alternate finite difference scheme based on eulerian approach is presented which avoids the error which arises when the advection portion of the advection-dispersion equation is solved numerically. The presented scheme is tested using some hypothetical, but rational, data for three different velocity profiles. The presented scheme, however, does not remove restriction on time interval (δt). The value of spatial grid interval (δx) is calculated by simple time of travel formula. The presented scheme eliminates a restriction imposed on spatial grid interval which prevails in the existing scheme. |
