Method synopsis

Use of small unoccupied aircraft systems with thermal infrared cameras to identify groundwater discharge zones in stream corridors through temperature contrast detection. Real-time thermal data visualization enables efficient location of preferential discharge areas.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Efficient hydrogeological characterization of remote stream corridors using drones (2018), Hydrological Processes. doi 10.1002/hyp.13332. Implementations in other papers (listed below) may differ.

1. Deploy sUAS from launch site
   Deployed a multi-rotor sUAS (3D Robotics Solo) from the northern bank of Oh-Be-Joyful Creek, adjacent to the Peeler fault zone. The launch site was approximately 2.4 km from the lower parking area using a rough path that climbs approximately 130 m in elevation.
   Quantities: One sUAS deployment, 2.4 km distance from parking area, 130 m elevation climbDuration: Less than 45 minutes total flight timeConditions: August 17, 2017, afternoon data collection in mid-August with mixed stream temperatures approaching 15°C and expected groundwater discharge temperatures less than approximately 8°C
   Equipment: 3D Robotics Solo, multi-rotor sUAS
2. Collect thermal infrared data
   TIR data were collected using a gimbal-mounted FLIR VUE Pro R 13mm camera that can store color video relative to a colorbar scale, or radiometric still images of apparent temperature. Data stream was visible on the sUAS hand controller during flights for real-time identification of potential groundwater discharge zones when they were either the coldest or warmest features along the river corridor.
   Quantities: Thermal data along several hundred meters of stream corridorDuration: Part of the 45-minute total flight timeConditions: Video colorbar set to autoscale during afternoon flights when sufficient thermal contrast existed
   Equipment: FLIR VUE Pro R 13mm camera, gimbal mount, sUAS hand controller
