Abstract
The idea of hydraulic continuity has been accepted some 20 years ago and is now accounted in river planning and training, e.g. in flood retention by upstream storage. By comparaison, the effectivness of sediment continuity is still often neglected. The main reason is a difference in its perception, which is due to much longer time scales of associated effects. The presentation is intended at demonstrating the conditions and various effects of sediment continuity. Special attention is paid to how the river answers to perturbations or breaking of this continuity.
