Short summary
We studied the propagation of natural and human-induced perturbations in large braided sand-bed rivers using a physics-based 3-D model. The results show that the perturbations not only affect the local morphology but their effects amplify while propagating through the braided network. This occurs by destabilization of bifurcations in combination with reshaping of bars and branches. These results could have a major impact on the assessment of engineering measures in large braided sand-bed rivers.
