Towards Living with Water

Abstract

As a result of global warming sea levels have recently started to rise and pose threatening scenarios to increasingly densifying urban areas worldwide. As the low-lying Netherlands will be one of the first to witness the consequenses of rising sea levelsa and increasing river water discharge, alternatives for its built environment will have to be explored in order to be able to adapt in time. As the Netherlands has been successfully holding off the water for decades, the country is globally seen as a pioneer in water management solutions. Therefore the Dutch are in the position to lead by example. However, the phenomenon of rapidly accellerating sea level rise is something Dutch water management has never dealt with before. Uncertainty and rapidly changing predictions make it difficult to decide on drastic and costly measures in time. In order to facilitate a transition from the established defensive landscape towards living with water instead, a new flood resilient building type can facilitate in adapting to near future predictions, while also raising awareness for the urgency of rising water levels and contributing to the current housing shortage. In order to achieve this it is necessary to step away from the defensive landscape and outdated water management strategies. This research will elaborate on predictions regarding sea level rise and changing weather conditions in the densifying outer dike area of the urban center of Rotterdam. Contemporary approaches towards building dikes, the importance of engaging private parties in generating flood resilient solutions and the possibility to utilize water and flood defence barriers as a flexible building ground in densifying urban areas will be discussed. Ultimately leading to a novel mixed-use housing typology with the overarching goal to reduce the flood risk in densifying outer dike areas and contribute to a changing mindset towards living with the increasing risk of flooding.
