摘要: AbstractAnalytical solutions of one-dimensional (1D) advection-diffusion equations (ADE) are obtained subject to an initially pollutant-free domain and varying pulse-type input conditions. The medium is considered heterogeneous semi-infinite extent. heterogeneity defined by considering the velocity as a spatially dependent, linear, non homogeneous increasing function. It interpolated in finite which concentration values be evaluated. unsteadiness exponential form dispersivity also considered. expression for written degenerate form. Analytical when depends upon velocity. Laplace integral transform technique (LITT) has been used.
