With regard to river engineering, in the present-day cultural landscape, ecological aspects and adjusted perceptions are considered more and more. The Instream River Training is a technique of nature-orientated river engineering, making it possible - by minor interferences - to stabilize rivers as well as initializing its own dynamic and providing a sustainable bedload management at the same time. Thereby, the stream flow is regarded as cause of most issues regarding conflicts between human requirements and those of nature. The structural elements used for the Instream River Training are under way. By the development of an aim/consequence-matrix, the presented master thesis provides an opportunity to understand and discuss the aims and consequences of the river engineering measures by the principle of the Instream River Training. The objective is to improve the prognosis concept of those and comparable measures by an analysis of projects. Incipiently, the challenges of modern nature-orientated river engineering in relation to the legal framework are commented, and the development as well as the principle of the Instream River Training is defined. The individual construction methods are presented and consisting projects are used as base of the evaluation by the aim/consequence-matrix. After the explanation of the methodology, the analysis is conducted. In the conclusion, the results are summarized and discussed and a perspective - regarding the further development of the In-stream River Training - is given.
