The USGS Hydrogeophysics Branch is evaluating the integration of small unoccupied aircraft systems – sUAS or "drones" –  into USGS hydrogeophysical studies.

The sUAS sector is advancing rapidly through:

This combination of factors is enabling increased use of sUAS as accessible, cost-effective, and safe tools for low-altitude deployment of scientific sensors.

Potential Value to Hydrogeologic Field Studies

Integration of sUAS into groundwater studies will expand USGS capabilities to collect and use hydrologic information to improve our understanding of groundwater availability and quality:

HGB Evaluation and Integration of sUAS

There is significant interest in the application of sUAS-borne scientific sensors to USGS hydrogeologic studies, especially groundwater/surface-water exchange studies. HGB is evaluating the potential for cost-effective, operationally feasible integration of sUAS-borne sensors into USGS hydrogeophysical studies.

Initial efforts are focusing on evaluation and demonstration of hydrogeologic data collection with natural color, multispectral, and thermal imaging sensors on 3DR Solo quadcopters. Longer term HGB efforts include assessment of new and emerging sUAS geophysical sensors, such as ground-penetrating radar.

Thermal infrared image collected using a drone. In the image, the large yellow area in the upper left half is a stream, and the blue areas in the lower right are wetlands. The red area in the center of the image along the edge of the stream is relatively cooler groundwater discharging into the stream. The dark blue square is a ground control point, where the exact location is known and can be used to more accurately georeference the thermal imagery. Credit: USGS. Image is in the public domain.

Policy and Background Information

Sensors and aircraft used by HGB must be approved for use by the USGS UAS Project Office and Department of Interior (DOI) Office of Aviation Services. HGB remote pilots are carded for operations by the Department of Interior and certified Remote Pilots under the Federal Aviation Administration's Part 107.
