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.
沉积物是我们流域的一个基本、不可或缺且动态的组成部分。一条健康的河流需要沉积物作为生命之源。不幸的是，沉积物也可能成为许多有害化学物质的汇。当污染达到一定程度时，这将导致负面影响，如生物多样性丧失。社会认为这是不可容忍的，因此制定了欧洲水框架指令（WFD）。WFD旨在到2015年使所有欧洲水域达到良好状态。WFD虽未专门涉及沉积物问题，但沉积物质量与实现该WFD目标之间显然存在联系。然而，与沉积物监测相关的是，WFD中有一些直接联系，本文将对此作进一步解释。
