Abstract

Studies on the potential hazard of a contamination often use flowpath simulation as a technique applied in combination with a flow model. Some numerical aspects and alternatives are presented and evaluated. The time- integrated approach turns out to be the method of choice. For the mentioned purpose the application of particle tracking should be used with care, because it is not conservative. The danger may be underestimated in areas transverse from the pathlines downstream from a contaminated site. 1 Introduction In hydro-engineering practice it has become a widespread technique to use particle tracking as post-processing tool to a flow model. The visualisation of the flow pattern by pathlines resp. streamlines is used for different purposes. Reilly & Pollock [10,11] study areas con
