Abstract
The river Rhine is Europe’s economic powerhouse. Without the Rhine, the Ruhr area and the port of Rotterdam wouldn’t have developed into the economically leading industrial regions they are today. The economic power of the Rhine comes forward from the ability of humans to control the river. By rectifying and canalizing the river and constructing dams and locks, the ships’ ability to navigate the river increased. This focus on economic development has caused critical environmental problems. Floods, droughts, and pollution are the most notable environmental threats to humans. This is intensified by climate change as extreme rainfall events and periods of drought will become more severe. Our current paradigm in flood risk management tells us to endlessly keep heightening our dykes, which is not a sustainable path to deal with flood risk. Heightening dykes also leads to shifting the problems elsewhere. If a river is not given space to flood its natural floodplains, it is forced to flow downstream more quickly, leading to a higher peak water level and potential floods downstream.
This master thesis introduces the concepts of socio-ecological symbiosis and clearance as means to improve water safety, the connection between humans and water, and the natural habitat. The central question of this research is: How could water safety downstream be supported by upstream design interventions in the Northern Upper Rhine Valley, based on methods in which socio-ecological symbiosis and clearance are central? As upstream water management strongly influences the downstream water safety, design exercises are executed in the Northern Rhine Valley with the goal to improve the water safety both downstream and locally. Three typological design exercises are set up which together form the proposed future water management strategy of the whole Rhine Valley.
