✓ Detect and geolocate easily and quickly individual particles distributed over large areas and in landfill situations.
✓ To be able to equip particles of the smallest possible size.
Regarding the technical operation, this solution is based on a set of artificial pebbles integrating COIN ID Active RFID tags. These last ones are introduced and geolocalized in the bed of a river. During floods, the pebbles are transported in the river bed by the flows. Once the floods have passed, the researchers go to the field to geolocalize the pebbles thanks to a detection system composed of an antenna and an RFID reader. Three different detection techniques are used:
• Either by a fixed station which timestamps the passage of the pebbles.
• Either by teams of 2 to 3 people on foot.
• Either by drone equipped with a Slender antenna and a GPS to geolocalize in the clear spaces.
✓ High return rates compared to previous similar studies (No. of objects found / No. of objects deployed)
✓ An opportunity to study very dynamic rivers, with very large sediment transport distances
