ABSTRACT
In order to use the permeable wall process for securing and rehabilitating contaminated aquifers, the knowledge of the existing hydrogeological situation on site has to be extremely high. To minimise expensive sampling, computer models can be used to calculate and view different possibilities to construct and place the wall in the underground. The paper presents resent research work, where shape and location of a permeable wall and its impacts on the hydrogeology have been investigated using computer models. It also gives an introduction to the permeable wall technology. It is shown, that the computer models functions very well as an aid for deciding shape, length and permeability of the wall; especially the dimensions of the wall, which combines optimal operating conditions and low construction costs, can easily be found and viewed.
