Abstract: This paper presents a numerical solution of the advection-dispersion equation (ADE) with the varying dispersion coefficient and velocity. Contamination of water decreases the quality and quantity of groundwater as well as surface water. Hydraulic conductivity and water retention property also affect the groundwater solute transport model in the vadose zone. The mass balance equation and governing equation of solute transport of advection-dispersion both are interrelated. the governing equation is formulated using Darcy’s law and some basics concept of groundwater flow. In the governing differential equations solved numerically. The Equation containing all the parameter and it is a program on the MATLAB and the equation is applicable in the entire situation which is saturated or unsaturated zone. The model is generated for all condition and which tested for taking many sample problems. The numerical solution is more effective and more sensitive used for the to the groundwater solute-transport. The set of programs created and evaluated these solutions. This solution contains many structures that improve their precision, ease of use and its validity. the analysis of Advection-dispersion equation FDM MATLAB code is developed to obtain the numerical solution. Derivation of most of the solution, MATLAB codes for programs, and samples of program input and output are included. In the present paper, the finite difference model developed to asses for groundwater solute transport model for advection and diffusion in the saturated aquifer.
