the groundwater modelling group, we are developing a 0-dimensional model for the
large scale water balances for a part of the Eckernfoerder Bay which gives the
input for a regional scale model that is developed by other partners.
In the figure above, the mesh and the boundary conditions for the Henry problem are shown. Initially, the system is filled with fresh water. On the left boundary fresh water influx is prescribed, on the right boundary a hydrostatic pressure distribution.
The two phase flow concept assumes that fresh and salt water are different phases which are not soluble in each other, and consequently, these two liquids are seperated by a sharp interface. The single phase / two component concept takes into account that fresh and salt water are miscible. Thus a mixing zone occurs, where the salinity gradually changes due to hydrodynamic dispersion.
