To avoid depth erosion in rivers and to maintain the safety and ease of navigation, sediment-management measures have to be taken in Federal waterways (dredging, artificial supply and translocation of sediment). Here, we pose the question whether sediment management has any influence on the fauna of the riverbed. To answer this question, the macrozoobenthos was compared between stretches with and without management, both in the rivers Elbe and Main. In these two rivers, sediment management is performed regularly with average intensity. The results show that the intensity of sediment management - with the current practices - does not have any influence on the distribution structure of macrozoobenthos.
