Geophysical Data and 3D Model for a Study of Ground Subsidence from Internal Erosion

Supporting information for the 2026 paper 'Study of ground subsidence due to internal erosion in sands using ground penetrating radar profiling and induced polarization tomography'. The dataset contains additional ground penetrating radar (GPR) and induced polarization tomography (IPT) data, along with a 3D geological model. It was authored by Dave Bédard and others, and harvested into the Borealis Dataverse repository.

Use Cases

• Validate geophysical inversion models based on the provided ground penetrating radar and induced polarization tomography data.
• Study the relationship between internal erosion processes and ground subsidence based on the 3D geological model.
• Benchmark new subsurface imaging algorithms against the collected GPR and IPT profiling data.

Strengths

• Data is directly linked to a specific 2026 peer-reviewed research paper, providing context.
• Includes multiple complementary data types: GPR profiles, IP tomography, and a 3D geological model.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
