Successfully transforming riverscapes depends on regional cooperation and transdisciplinary collaboration. Spurred on by the European Water Framework Directive, many European regions are working on improving the ecological quality of rivers and reshaping the adjacent landscapes. So, planning teams consisting of landscape architects, urban planners, architects and ecologists work on integrated strategies for designing sustainable riverscapes. To make sure that these strategies are supported by regional key actors and can thus be implemented successfully, co-creative processes are needed. Through reflecting on experiences and findings from projects of my design practice, I have identified three key success factors for successfully designing riverscapes in a co-creative manner: Walk! Find typologies! Design spatial visions! These success factors are discussed in the light of recent publications on landscape architecture research. Finally, interconnections with the topic of urbanization and locality are shown. Find the text in the book Water-Related Urbanisation and Locality!
