Abstract

The application of a 3-dimensional geoscience information system (GSIS) in the performance assessment of the geological barrier of the nuclear waste disposal site Morsleben is presented. A primary objective is the development of a geometrically consistent three-dimensional model, representing all relevant hydrostratigraphic units in the model area. Following the completion of the structural model, Finite-Element mesh generation techniques are applied to derive a threedimensional spatial discretisation for numerical modelling of the regional groundwater movement.
