Abstract:
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.

| 8 | Length, b-axis, representative | Repr b-axis | m | Klösch, Mario | Axis lengths and mass were measured on grains sampled at the sediment transport monitoring station in Dellach an der Drau. Mean axis lengths and masses of grains representing each size class were calculated and served as target values for the selection of natural model stones for creating the molds for tracer production. Since the selection of model stones was not only based on the b-axis (the lengths of the a-axis and the b-axis as well as the mass were also taken into account), the representative b-axis length was used in the corresponding publication. | |
