Water Ecology

Surface waters in transition

Dealing with landscape and water has undergone a significant transition over the last decades.

Since the European Water Framework Directive has entered into force, water bodies must be restored into a “good status”, i.e. they shall differ just slightly from the natural state. AKUT has made innovative contributions in this field, for example when improving the linear patency of running waters of Nonnenfließ using wooden constructions or by increasing nutrient retention from diffuse sources in the catchment area of the lake Schwielochsee with use of wetland technology.

Not least water treatment for swiming ponds in wetland systems (closed cycles) as well as achievement of bathing water quality in public waters (open waters) under the EU Bathing Water Directive plays an important role. For both AKUT has developed standalone solutions for modern watershed development concepts.

AKUT develops customized solutions in cooperation with regional and local partners such as architects, landscape architects or water maintenance associations.

Rehabilitation of Natura 2000 area

Barnim, Germany, 2008

In wide parts the regional landscape water resources in the state of Brandenburg are out of balance.

Due to its richness in flora and fauna the protected Natura 2000 area (EU Habitats Directive) Nonnenfließ/Schwärzetal is the most valuable water stream of the Barnim Nature Park and some parts are a reference water of the state of Brandenburg. Human activities do have negative impact in regards to decisive ecological parameters such as ecological passability, water retention, structural diversity and biodiversity. more >
