Solute Transport for Pulse Type Input Point Source along Temporally and Spatially Dependent Flow

In the present study, analytical solutions are obtained for two-dimensional advection dispersion equation for conservative solute transport in a semi-infinite heterogeneous porous medium with pulse type input point source of uniform nature. The change in dispersion parameter due to heterogeneity is considered as linear multiple of spatially dependent function and seepage velocity whereas seepag...

Modflow/mt3dms-based Simulation of Variable- Density Groundwater Flow with Simultaneous Heat and Solute Transport

SEAWAT is a finite-difference computer code designed to simulate coupled variabledensity ground water flow and solute transport. This paper describes a new version of SEAWAT that adds the ability to simultaneously model energy and solute transport. This is necessary for simulating the transport of heat and salinity in coastal aquifers for example. This work extends the equation of state for flu...

Two-Dimensional Solute Transport with Exponential Initial Concentration Distribution and Varying Flow Velocity

The transport mechanism of contaminated groundwater has been a problematic issue for many decades, mainly due to the bad impact of the contaminants on the quality of the groundwater system. In this paper, the exact solution of two-dimensional advection-dispersion equation (ADE) is derived for a semi-infinite porous media with spatially dependent initial and uniform/flux boundary conditions.
