Abstract

It is widely accepted that an integrated characterization approach is necessary to define the geometry, internal structure, material distribution and water composition of aquifers. Multiple geophysical and hydrogeological data were measured in the sub-watershed surrounding a former unlined landfill: hydrogeological data in 25 direct push full-screen wells (slug tests, water conductivity, water levels), 21 km of GPR, 5 km of 2D electrical tomography and 30 cone penetration tests (CPT) with soil moisture resistivity (SMR). The 3D data integration in gOcad facilitates data interpretation and provides the basis for a detailed numerical groundwater flow and transport models.
