Keywords:Drone Airbrne Survey, D-GREATEM, D-TEM

To examine the effectiveness of drone airborne electromagnetic survey methods, (aerial transmission type: D-TEM and ground transmission and aerial reception type: D-GREATEM), survey was conducted in the Seino area of Gifu prefecture.
The purpose of the survey is to understand the alluvial fan-shaped gravel / alluvial cohesive soil, fault structure, and hydraulic characteristics.
The survey was conducted twice during the heavy rainy season (September) and the light rainy season (December) to detect changes in groundwater.
A three-dimensional resistivity model was created from the survey results, and the resistivity structure, geological structure, and irrigation structure were considered.
Moreover, the applicability of the two survey methods to groundwater surveys and exploration capabilities were verified.

This survey was conducted by the Strategic Innovation Creation Program (SIP) "Strengthening National Resilience (Disaster Prevention and Mitigation)" (Management Corporation: Disaster Prevention Science and Technology Research Institute) of the Council for Science, Technology, and Innovation of the Cabinet Office.
