Abstract: In this study we conduct some specific experiments to investigate the effects of stem density and flow velocity on the interaction processes between two types of particle and emergent vegetation in an open channel flow. We propose a new definition of the probability that a particle interacts with a stem which seems more plausible, and preliminarily explore the particle-stem interaction processes (interaction and capture). We also determine a length scale to assess the model performance (for vegetation characteristics and arrangement in this study) and propose a dimensionless parameter to evaluate the adsorption capacity for the floating particle attached to the stem. Some experiment phenomena have been observed in this experiments were presented for further analysis and research
