Description	We present a problem-suited numerical scheme for solution of variable-density groundwater flow and solute transport problems and its application in the remediation of Straz pod Ralskem uranium leaching site.The numerical scheme is a combination the FEMon 2D triangle mesh and finite differences in the vertical direction (1D columns of mesh nodes). We derived the discrete form of theadditional variable-density term, keeping the local mass balance in the both flow and transport numerical schemes. We demonstrate the use of the scheme in a basic benchmark problem,confirming the importance of influence of gravity on dense contaminated solutions and natural water movement with hydralic forces in this site.

(en) Prezentujeme numerické schéma pro řešení podzemního proudění a tarnsportu látek s proměnnou hustotou, přispůsobené aplikaci při sanaci lokality Stráže pod Ralskem.Schéma je založeno na kombinaci metody konečných prvků na 2D trojúhelníkové síti a konečných diferencí ve svislém směru. K tomu byl odvozen postup pro diskretizaci doplňkového členu proměnné hustoty,které zachovává vlastnosti bilance látky v obou modelelch proudění a transportu. Demosntrujeme použití schématu na základní benchmark problmém,který potvrzuje důležitost vlivu hustoty a gravitace na hodně koncentrované roztoky. (cs)
