Short description: Geophysical measurements are becoming more and more essential for subsurface investigations for environmental and infrastructure projects. GeoPASS assists you in selecting the optimal geophysical technique for your survey. 
Long description: GeoPASS includes modules for: electrical resistivity method electrical resistivity tomography (bore hole to bore hole) time domain electromagnetic methods electromagnetic induction method (conductivity meters) ground penetrating radar (50 MHz and a user selected frequency) induced polarisation metallic object detection (includes magnetic method and metal detectors) seismic reflection techniques spectral analysis of surface waves The geophysical methods can be assessed on the detection chance on four target categories: layers (including LNAPL's) pollution plumes DNAPL's/solid waste/objects/cavities fractures
