Positions of bedload tracers in an alpine section of the Drava River after seeding on 11 May 2017 up to 11 June 2018

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.本数据集关联2017年5月11日至2018年6月11日期间，在德拉瓦河（Drava River）阿尔卑斯河段开展的底沙示踪剂（bedload tracer）野外研究工作。2017年5月11日完成示踪剂投放后，研究团队通过搭载天线、接收机与全球定位系统（GPS）的船载平台开展了10次搜寻，本数据集收录了此次搜寻获取的全部底沙示踪剂位置信息。本次研究共投放65个人工底沙示踪剂，所有示踪剂均模拟了覆盖5个粒径粒级的5类代表性天然泥沙颗粒的形态特征。此外，本数据集还提供了布设于示踪剂投放点位下游约5公里处的固定天线的观测记录。
