|
* \brief Isothermal NAPL infiltration problem where LNAPL
|
|
* contaminates the unsaturated and the saturated groundwater
|
|
* zone.
|
|
*
|
|
* The 2D domain of this test problem is 500 m long and 10 m deep,
|
|
* where the lower part represents a slightly inclined groundwater
|
|
* table, and the upper part is the vadose zone. A LNAPL (Non-Aqueous
|
|
* Phase Liquid which is lighter than water) infiltrates (modelled
|
|
* with a Neumann boundary condition) into the vadose zone. Upon
|
|
* reaching the water table, it spreads (since lighter than water) and
|
|
* migrates on top of the water table in the direction of the slope.
|
|
* On its way through the vadose zone, it leaves a trace of residually
|
|
* trapped immobile NAPL, which can in the following dissolve and
|
|
* evaporate slowly, and eventually be transported by advection and
|
|
* diffusion.
|
|
*
|
|
* Left and right boundaries are constant hydraulic head boundaries
|
|
* (Dirichlet), Top and bottom are Neumann boundaries, all no-flow
|
|
* except for the small infiltration zone in the upper left part.
