November always seems like the rainiest of Danish months, but it isn't, actually. October is. But November feels rainier, because the sky is so grey, and it gets dark so early, and the rain sometimes comes down in little freezing pellets.

Denmark is a watery country, not just its long coastline and many rivers and lakes, but also the fact it is mostly near sea level. Like the Netherlands nearby, it is extremely vulnerable to flooding.

Climate changes in recent decades have made it worse, and sudden cloudbursts – or skybrud– cause a lot of damage.

So retrofitting Denmark for even more water in the future has become a national obsession.

One popular solution: opening up previously buried rivers and streams, particularly those that were paved over with concrete.

This "daylighting" of buried waterways allows them to collect excess water from storms, and beautifies cities as well.

This is the most recent episode in our 12-part series, The Danish Year.
