An Investigation of Dispersion on Tracer Transport through Variably Saturated Porous Media Using VS2DT Modelling

An Investigation of Dispersion on Tracer Transport through Variably Saturated Porous Media Using VS2DT Modelling The objective of this study is to investigate dispersion on tracer transport through variably saturated porous media using Vs2dt modeling. To investigate the tracer transport a numerical model is developed according to the advective dispersive contaminant transport equation in saturated porous media with the help of Vs2dt software. Pressure head, Total head, Concentration profile and velocity vector configuration is shown below by different bitmap images. The results reveal that the enhancement of dispersivity induces the flow path distance and decreases of pore velocity. Using the coloured images the range of variations has been investigated. The tracer transport affect can be perfectly viewed in the computational domain
