  • Accuracy of automatically extracted geomorphological breaklines from airborne LiDAR curvarure images
  • , slope and sinuosity are computed and compared to reference data. The properties are discussed regarding their explanatory power with respect to accuracy and precision. Automatic extraction results strongly differ from manually digitized breaklines

  • In the Erlenbach stream, sediment transport has been continuously monitored with piezoelectric bedload impact and geophone sensors since 1986. In 2008-2009, the measuring system was enhanced by installing an automatic system to obtain bedload
  • samples. Movable metal baskets are mounted on a rail at the downstream wall of the large check dam above the retention basin, and they can be moved automatically into the flow to take bedload transport samples. This upgraded measuring system permits
