Rijkswaterstaat - The Dutch National Forecasting System

A large part of our country lies below sea level, which makes us vulnerable to flooding. Protection against flooding will always remain vitally important. Rijkswaterstaat monitors water levels along the coast, in rivers and in lakes.

We issue early warnings of a threat of storms and high water levels, so that water authorities can take action before there is any real danger. If necessary, we close the storm surge barriers.
