Abstract: The quantification of large wood dynamics within river networks is crucial for managing rivers under contemporary human pressures, but still we need a better understanding of the factors controlling wood mobility, especially in large multithread rivers. Large wood promotes fundamental changes in rivers sedimentology, hydrology, hydraulics, and morphology, playing a relevant role in the river ecology but also in flood hazard and risk. Despite the large body of research about large wood in rivers, knowledge about large wood dynamics in braided rivers is still limited. Most studies generally concentrated in small rivers and less is known about the recruitment, transport and deposition of large wood in larger and more complex riverine environments. Important knowledge comes from flume experiments, remote sensing and more recently, numerical modelling. However, these three approaches were never combined so far. This work aims to fill this gap, combining the analysis of aerial pictures and field surveys, with the numerical modelling of flume experiments to study different aspects of large wood dynamics in braided rivers.
