Abstract

Location of flow field boundaries is probably the first step in the numerical solution of groundwater flow and mass transport problems. In case studies, these boundaries usually have to be simplified, deduced from insufficient data or even assumed. Such approximations may be a source of error in the numerical results. Boundary element schemes are probably the most vulnerable, since hydraulic heads and velocities in the interior of the flow field are calculated from the same quantities on the field boundaries. To explore this source of error, a typical groundwater contamination problem, involving contaminant injection and production wells, has been investigated, by means of a boundary element and particle tracking technique. Results show that reasonable field boundar
