Abstract

The study of bedload transport processes is constrained by an inability to monitor the mass, volume and grain size distribution of sediment in transport at high temporal frequencies. Building upon a previously published design, the AA. have integrated a high-resolution video camera with a light table to continuously capture images of material exiting a flume. The images are continuously recorded at a rate of 15 to 20 frames per second and are post-processed using LabView software, yielding continuous grain-size-specific transport information on a per second basis. The video capture rate is sufficient to record multiple images of each grain leaving the flume so that particle velocities can be measured automatically. Discussion of the results
