The growing attention for the troubling effects of climate change, has resulted in an impulse for water management. How to deal with an expected rise of the sea level, increase of river discharge and more rain? As responsible for 'having and keeping a safe and habitable land and persisting and strengthen the health and resilience of water systems, which guarantees sustainable use', water managers have taken up the challenge (Ministerie van Verkeer en Waterstaat, 2000). The result, amongst others, is an ambitious national policy aiming to create more space for water (Tielrooij, 2000). The high ranking of water safety and water supply on the national political agenda, does apparently not result in prioritizing the stake of a sustainable water system when dealing with other stakes in spatial development. This makes sense to perform a research on the current and desired approach for water management by focusing on the role of project leaders of waterboards.
