This report is generated by an automated decision-support tool using generalised geophysical guidelines and does not constitute professional engineering advice. All recommendations must be reviewed, validated, and adapted by a qualified geophysicist or geotechnical engineer with knowledge of the specific site conditions, project requirements, and applicable standards. The tool authors accept no liability for decisions made solely on the basis of this advisory output.
A free, professional decision-support platform for near-surface geophysical method selection — built for civil, geotechnical, dam, tunnel, mining, and environmental engineers.
When Expert Mode is enabled, the following additional input fields become visible throughout the Method Advisor wizard:
4-step structured questionnaire covering problem type, investigation requirements, site conditions, and practical constraints.
Method selection rules based on established geophysical practice, adapted for 15+ common near-surface investigation scenarios.
Primary method, supporting combination, cautionary notes, suitability ratings, and a consulting-style recommendation report.
