FLOOD PROTECTION IN HIGHLY VALUABLE RIVER ECOSYSTEMS - MIDDLE DELTA SYSTEM OF THE NIDA RIVER

ABSTRACT
The Nida River, which flows across the central part of Poland, creates a unique inland delta in its middle run, inhabited by many rare plant and animal species. After river training and reclamation works conducted in the 1980's, retention capacity of the catchment has dramatically decreased. The run of the Nida River in the delta was shortened, which caused an increase in watercourse slope, resulting in the intensification of bedload transportation and bed erosion processes. At present, there are many ecological projects running in the Nida basin (i.e. the Natura 2000, Bird Directive, CORINE, etc). In order to improve the condition of water and flood protection in the middle delta, renaturalization works are proposed which safely restore valley retention.
Key words: flood defense, renaturalization, middle delta, multichannel system, landscape.
