USE OF STRATIGRAPHIC, PETROGRAPHIC, HYDROGEOLOGIC AND GEOCHEMICAL INFORMATION FOR HYDROGEOLOGIC MODELLING BASED ON GEOSTATISTICAL SIMULATION

摘要

This paper describes the stepwise utilization of geologic information from various sources for the construction of hydrogeological models of a sedimentary site by means of geostatistical simulation. It presents a practical application of aquifer characterisation by firstly simulating hydrogeological units and then the hydrogeological parameters. Due to the availability of a large amount of hydrogeological, geophysical and other data and information, the Gorleben site (Northern Germany) has been used for a case study in order to demonstrate the approach. The study, which has not yet been completed, tries to incorporate as much as possible of the available information and to characterise the remaining uncertainties.
