Quaternary deposits and topography are two geological parameters which have a great impact on transport and retardation of radionuclides from a leaking repository of high level nuclear waste in crystalline bedrock. Due to the hydraulic and sorption properties of quaternary deposits, even thin layers significantly increase the residence time of leaking radionuclides. This study also shows that the flow paths predominantly discharge in low areas of the catchments where the layers of quaternary deposits often are relatively deep. The effect of topography is depending on the relationship between the local(kilometres) topography at the repository site and the large scale(hundreds of kilometres) topography surrounding the site area. The areas studied here, are located at discharge areas of deep groundwater flow, driven by large scale topography. Therefore residence times of radionuclides significantly decrease when large scale topography is accounted for. The impact of large scale topography is particularly clear in areas of flatter local topography.
