Within the span of two centuries, rivers of European cities have gone from serving as the dump site for all urban waste to being a vibrant natural environment integrated into the city.

It takes an interdisciplinary look from the perspective of the environment, technology and society to shed light on the relationship that four European cities (Berlin, Brussels, Milan and Paris) have with their rivers and their transformations since the 19th century.
