Hydrodynamic (fluid flow) problems in general are actual from the wide points of view. The ecological catastrophe in the Czech Republic (2002), especially flooding of Pilsen, gives us new impulses for numerical simulation of particular fluid flow problems. Here we discuss two variants of...

This paper employs a two-dimensional variable density flow and transport model to investigate the transport of a dense contaminant plume in an unconfined coastal aquifer. Experimental results are also presented to show the contaminant plume in a freshwater–seawater flow system. Both the...
