In this article, drawn from displays and dialogue at a may well 2005 NATO complex examine Workshop, present methods to the evaluate and remediation of infected sediments are mentioned with emphasis on in-situ administration. The textual content addresses actual, chemical and organic techniques for the review and remediation of sediments. the advance of regulatory and strategic ways is mentioned with emphasis at the capability for organic remediation within the administration of infected sediments.

APPROACHES FOR MANAGING CONTAMINATED SEDIMENTS 21 Clean sediment can also have environmental and socio-economic impacts. For instance, turbidity and excessive sedimentation have a physical effect on benthic life, too much sediment in navigation channels requires costly dredging, and sedimentation behind dams decreases the economic lifetime of that dam. Furthermore, dams decrease the supply of sediment needed to support downstream wetlands, estuaries and other ecosystems. SedNet focused on contamination issues, rather than on such sediment quantity issues.

Org for workshop reports). Similarly, discussions of the European Soil Strategy grappled with how to make soil more 'sexy' to the same audiences (EEB 2002). Contributors to both the Soil Strategy and SedNet are generating documents and recommendations for the EC to convince them that the protection of soils and sediments are critical in holistic ecosystem management, but they are doing this largely in isolation from one another. Because soils and sediment management are, in reality, interdependent, these efforts should be combined.
