ABSTRACT
An analytical solution is obtained for the advection-dispersion of a constant input concentration along unsteady horizontal flow in semi-infinite shallow aquifer. Exponential form of time-dependent seepage velocity and first order decay are considered. Point source pollutant reaches the groundwater level from a surface and moves vertically down-wards, from its each point and starts spreading in the horizontal plane. Two separates transformations are introduced. Laplace technique is used to obtain the analytical solution of the present problem.
