Heavily modified waterbodies - HMWB

Representation of heavily modified waterbodies which have been physically altered by human activity that they can not achieve good ecological status as defined by the water framework directive (DIR 2000/60/CE) and that no technical feasibility or cost-effective option exist to stop that human activity. These water bodies have the good ecological potential as the environmental objective. They have nevertheless to achieve good chemical status.

表征受人类活动剧烈改变的水体，这些水体因物理形态的改造而无法达到《水框架指令》（DIR 2000/60/CE）所定义的良好生态状况，且不存在技术可行性或成本效益的方案来阻止此类人类活动。尽管如此，这些水体在环境目标上仍具备良好的生态潜力，但仍需实现良好的化学状况。
