Water quality assessment of a Central European River — Does the Directive 2000/60/EC cover all the needs for a comprehensive classification?
Abstract Over the last decades, European rivers have mostly shared the same fate. Until the mid 1980s many of them were in rather bad shape. Nobody would have thought about using the waters for recreation. However, continuous efforts over the last...
