In the Building with Nature project, the Noorderzijlvest district water board is collaborating with partners from the Netherlands, Norway, Sweden, Denmark, Germany, Belgium and Scotland to design a natural defence against floods. We can protect areas from flooding with dams and dikes, but natural defences against the water exist as well. In ‘Building with Nature’, the effects of 13 natural interventions are collected and monitored. These will form the base for future adaptations.
