History of a Polder

In the beginning, the water cycle is dominant. 

The moon is controlling the tides and the sun determinates the rivers discharge. 

The West is a tidal basin at that time.

The tidal basin is filled with clay and peat. 

From the Middle-ages the peat was used for heating. 

Many lakes were formed by man. 

And turned to polders.
