Abstract: The use of radio transmitters to track and locate coarse sediment (39 mm or larger) was successfully demonstrated by tracking five individual rocks through a highly mobile, braided river system. Radio-implanted rocks traveling distances greater than 1,500 m in 8 days time were tracked during periods of high flow and turbid water conditions. After flow receded and access to the bars and channels was possible, the rocks were again located and recovered even though burial of up to 0.3 m had occurred. A motion sensing device which detects whether a particle is in motion or at rest was also tested successfully.
