--- The big flood in the upper Elbe River catchment area
has revealed a wide spectrum of problems with contaminated
sediments. So far, an effective strategy for managing contaminated
sediments on a river basin scale is still missing and it seems
that not much has been learned from the lessons received during
the last decade.
In the following overview, special emphasis is given to the utilization
of geochemically-based techniques for sediment
remediation, which can be applied in different parts of a river
basin. The examples presented here are mostly from the Elbe
River catchment area. In general, new technical problem solutions
need a set of practical process knowledge that uses a wide
range of simulation techniques, as well as models in different
spatial and temporal scales.
The evaluation of recent flood events clearly demonstrates the
importance of chemical expertise in the decision-making process
for the sustainable development in river basins.
