B037 GEOPHYSICAL INVESTIGATIONS OF A WASTE DISPOSAL IN URBAN ENVIRONMENT 1 DANIEL FIELITZ MANFRED DEGUTSCH Institute of Geophysics Corrensstr. 24 48149 Muenster email: [email protected] Abstract An extended geophysical survey using magnetic resistivity and seismic methods has been carried out in a complicated area in the city of Muenster. The purpose was to map the boundary between an old waste disposal site and the underlying “Muensterlaender Kiessandzug”. The results reveal that the disposal extends to a depth of approximately 15m with resistivity values between 70 Ohm*m and 200 Ohm*m and p-velocities ranging from 400 m/s to 600 m/s.
