Properties and seeding positions of bedload tracers in an alpine section of the Drava River on 11 May 2017

This is a data set related to a bedload tracer field study in an alpine section of the Drava River between 11 May 2017 and 11 June 2018. It contains the characteristics and seeding positions of bedload tracers. A number of 65 artificial bedload tracers were equipped with active very high frequency radio transmitters imitating 5 natural grains representative of five grain size classes. The tracers were all seeded on 11 May 2017 in a cross-section across five points in the middle of the Drava River, 2.5 m apart laterally. Seeding was done from a boat in bags that contained the tracers and could be opened after they were lowered onto the riverbed.
