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 positions of bedload tracers as obtained during 10 searches from a boat with antenna, receiver and GPS after the tracer seeding on 11 May 2017. A number of 65 artificial bedload tracers were deployed imitating 5 natural grains representative of five grain size classes. In addition, the recordings from a stationary antenna, located about 5 km downstream from the seeding location, are provided.
