No. The country is protected very well.
I believe it is safe to say most rivers have flooded at one time or another.
Most parts of the Netherlands are below sea level / below the water level of the rivers that flow through the country. If there were no dams and dykes, those lands would be flooded.

The areas of the Netherlands that were once under water and now are land are called "polders". These are protected from being flooded with seawater by a system of dikes, canals, and windmills. There is a saying in the Netherlands that "God made the earth, but the Dutch made the Netherlands". Many people in the Netherlands live on land that is younger than they are.
