Concept for the near-natural development of rivers
A concept for the near-natural development of rivers ( water development concept , GEK ) is an expert opinion that describes the previous and present state of a river and its surrounding area (its floodplain ) and shows practical possibilities for near-natural expansion and maintenance measures on flowing water.
The main goal of a water body development concept is to derive measures that can be implemented in the short to long term, which help to approximate or achieve a natural state of the water body.
The concept represents a basis for the future annual maintenance planning. The implementation of the concept does not mean that the state developed as a model is achieved. The mission statement is for guidance only. The development goal represents the maximum approximation to a natural state of the water, which can be achieved in a manageable time frame, taking into account the given socio-economic conditions.
