Decision-making processes for clean-up of contaminated sites are often highly complex and inherently uncertain. It depends not only on hydrological and biogeochemical site variability, but also on the associated health, environmental, economic, and social impacts of taking, or not taking, action. These variabilities suggest that a dynamic framework...

Using open-access data sets on water and soil from Swedish authorities and compiling them in a QGIS-programme made it possible to present and visualise the water budget of the Lagan River Catchment.
