Natural, artificial and considerably modified

Even though, due to present uses many constructions are irreversi- ble, the waters concerned should be ecologically revalued to the greatest possible extent. At least the best possible status permitted by the existing uses should be rea- ched. This is true of considerably modified waters – that is, almost the entire Rhine and all of its most important tributaries – as well as of artificial waters such as chan- nels or flooded gravel pits. Only the character of the river Sieg and of the upper reaches of Neckar, Main, Moselle, Sarre, Ruhr, Lippe and Vechte is largely still natural.

Today, the status of almost the entire Rhine and of all major tributaries is considerably modified (May 2005).

Today it is forced into a fixed bed and deprived of its natural dynamics. the unnatural and monotonous state ubiquists with low demands to the ecological state dominate in the Rhine and its tributaries. With a view to improving biological diversity, rivers must become more varied and sub natural.

A state nearer to nature englobes more flood protection

Rhine 1838, source: Generallandesarchiv Karlsruhe Along the Rhine, flood protection is a permanent subject. Here, too, the ecological targets of the Water Framework Directive give new perspectives. Ecological diversity in- creases where rivers are re-natured, dead river branches are reconnec- ted and alluvial areas are re-estab- lished as floodplains. At the same time, natural flood retention areas form. Preventive flood protection is modelled on natural river land- scapes: Flood waves of rivers with enough space to brake the banks Rhine 1872, source: Generallandesarchiv Karlsruhe are less high.

Groundwater on the way towards the good quality status?

Groundwater is in the headlines once the damage has been done that is, once too high concentra- tions of nitrate or other noxious substances are found in a drinking water well. Then threshold values can only be respected by applying costly purification procedures. Groundwater is essential for man as well as for nature, e.g. in wet- land sites. Therefore, in future, it will be exhaustively protected. The current inventory proves that there are sufficient groundwater re- serves in almost all regions of the and that they are suf- ficiently recharged.

With a view to enabling such convergence and comparison in future, national and international experts must develop comparable procedures and criteria. Where it today seems improbable or unclear whether waters will reach the environmen- tal objectives, detailed monitoring programmes will start in 2006 and pressures will be closer analysed. Comparable biological and chemi- cal methods of measurement will lead to a definite classification of water bodies and appropriate measures will be planned until 2009.
