Denmark is implementing innovative solutions to combat the growing threat of flooding, with a focus on sustainability and climate resilience. One of the country’s most ambitious projects is the construction of a giant tunnel beneath Copenhagen, designed to handle excessive rainfall and prevent floodwaters from overwhelming the city. The tunnel will act as a giant reservoir, redirecting stormwater during heavy rains to prevent urban flooding. This initiative is part of Denmark’s broader strategy to protect its cities from the increased frequency and severity of floods due to climate change.
In addition to the tunnel, Denmark is also investing in creating “sponge parks”—green spaces designed to absorb and store rainwater. These parks feature permeable surfaces, trees, and wetlands that can capture rainwater and reduce runoff. The combination of the tunnel and sponge parks is part of a larger effort to make Denmark’s infrastructure more climate-resilient, helping to safeguard both urban and natural environments. By blending advanced engineering with ecological design, Denmark is setting a model for other countries facing similar flood risks. More
