The investigation aimed to identify differences between areas near the subterranean streams and those farther away. Results revealed that in regions potentially influenced by stream-related materials, HVRS spectral ratios displayed a characteristic double peak. This feature was absent in areas further from the streams. Similarly, GPR B-scans showed a significant increase in clutter within stream-affected zones, attributed to the geological composition of these areas. These findings highlight the effectiveness of combining HVRS and GPR techniques for characterizing subsurface features in areas with complex hydrogeological conditions. The study provides valuable insights into how subterranean stream dynamics influence geological structures, which is essential for engineering, environmental, and hydrological applications. 9 - Indústria, Innovació i Infraestructura Postprint (published version) Àrees temàtiques de la UPC::Enginyeria civil GPR HVRS shallow geology subterranean streams clutter cities Ground penetrating radar Geology Conferences Urban areas Soil Clutter Geologic measurements GPR HVRS shallow geology subterranean streams clutter cities GPR-based subsurface characterization in support of soil response studies
