Sediment monitoring and the European Water Framework Directive.

Sediment is an essential, integral and dynamic part of our river basins. A healthy river needs sediment as a source of life. Unfortunately, sediment also acts as a potential sink for many hazardous chemicals. Above a certain level of contamination this will result in negative impacts such a loss of biodiversity. This is deemed intolerable by society and hence the European Water Framework Directive (WFD) was developed. The WFD aims to achieve a good status of all European waters by the year 2015. The WFD does not specifically deal with sediment although it is clear that there is a link between sediment quality and achieving of this WFD objective. However, related to sediment monitoring there are some direct links in the WFD, which are further explained in this paper.
