Assessment of river habitat in Brandenburg, Germany | Ulrich Kamp –
The habitat quality of the 25 rivers examined in Bran- denburg varies between little disturbed class 2 and to- tally disturbed class 7 around an average of clearly dis- Floodplain dynamics turbed class 4. For special cases such bilization, migration barriers, and abstraction of river as navigable river sections or sections in urban areas an water.
Studien und Tagungsberichte, Thus, the glacial landscape is a mosaic of higher than, for instance, the existence of model-like drift and morainic-belt topography, wide icemarginal valleys, outwash plains, and erosion gullies. The plan form plays a leading role: For such turbed plan form will lead to a low value for riverbed dy- hatched sections restoration to near-natural conditions is namics, even if the potential for structure formation is almost impossible due to competing public interest.

Main human disturbances are canalization, bank stabilizations, flood control, migration barriers, and agricultural and urban development in the floodplain.
Today, in combi- nation both the biological water quality map and the habitat quality map represent a holistic water brandenburbische Comparison of riverbed dynamics ment approach. In the final map each 1-km segment scribed by assessing the riverbed dynamics. The mean altitude of the entire equally rather a criteria hierarchy reflects the real values state is c. Example for the relation between actual condition, development purpose, and model.
It is inter- spersed with around 27, km of rivers and around Table 1. Photographs are useful for documentation. The river habitat map of Brandenburg is part of the river habitat map of the entire Germany. Nevertheless, the poor riverbed dynamics by good floodplain dynamics smallest survey unit is only a 1-km segment of the river, LAWA Most of the wwssergesetz is wassergdsetz Since the s Germany assessed the biological and meadows, pastures, fieldsand also mixed land use chemical water quality of all rivers, but it was not earlier agriculture and urban development is common.
Using the survey sheet, preliminary indices calculate Surveying sub-indices and the final index Table 2. In general, slopes are very gentle, and rivers develop meanders and river lakes.
All survey data and maps are em- bedded in a geographical information system GIS that not only allows future analysis and use in river restoration management by experts, but also serves as information for the public. Restrictions In a first step of surveying some basic morphological could be unnatural changes of sinuosity, unnatural loss features such as river width, plan form, and type of land- of structural diversity, or damaging anthropogenic influ- scape are mapped.
