| Short description: |
This report gives a review of the existing practices in dredging management for the example estuaries
in the partner countries. Discussions led to a review of the issues that need to be considered when
assessing the potential impacts of dredging activities in estuaries with respect to European legislation. It
is recognised that estuaries are highly dynamic systems. As a result, a conceptual understanding of the
physical processes and geomorphologic dynamics of the system is needed. This must take into account
not only the natural variability, historical developments and ongoing trends, but also the effects of all
uses and users, of which dredging is only one. The significance of any effects of dredging should be
based on the understanding of the particular estuary system. However, it must be clear that this
understanding is still quite limited and the assessment of the effects must rely, among other, on
expertise.

| Long description: |
The morphology of an estuary is continuously changing, adjusting to the forcing processes which
themselves are also changing. No estuary is therefore stable and habitats and the ecological
functioning of the estuary will continuously change from its present status even if man did nothing
further. This implies the need for a detailed conceptual understanding of the estuary system in question.
Only such an understanding can lead to proper assessment of the effects of existing and future
dredging activities. Dredging is only one of the activities in an estuary. For any estuary there should be
a holistic management plan, including that required by the European Directives, which takes into
account the interests and effects of all uses and users of the estuary in an integrated way. Because of
the uncertainties, management must rely on historical analysis of past impacts and on a comprehensive
monitoring of the river response to dredging.
