Empoldering refers to the creation of polders.
A polder is a piece of land in a low lying area reclaimed from a body of water by building dikes and by drainage.
Empoldering can be carried out in coastal and inland areas such as lakes.
Features of polders
Dikes protect the polder from erosion
Drainage canals carry away excess water from the polders
in north of Amsterdam
A typical pasture area with high water levels and extensiveagriculture.
Method Of Empoldering
Reclaimed Area Of Netherlands
-A new bay called Zuider zee was created over the former farmland.
- The Dutch worked to slowly push back the water of the Zuiderzee, building dykes and creating polders.
- Once the dykes were built, canals & pumps were used to drain the land.
-From the 1200s, windmills were used to pump excess water off the fertile soil; today, most of the windmills have been replaced with electricity- and diesel-driven pumps.
dykes and works were built, reclaiming
the land of the IJsselmeer.
The new land led to the creation of
a the new province of Flevoland.

Today, approximately 27 percent of the Netherlands is actually below sea level. This area is home to over 60 percent of the country\'s population of 15.8 million people. The Netherlands, which is approximately the size of the U.S. states Connecticut and Massachusetts combined, has an approximate average elevation of 11 meters (36 feet). The Netherlands ties Lemmefjord, Denmark for claim to the lowest point in Western Europe - Prince Alexander Polder lies at 23 feet (7 meters) below sea level.
This defence line is the only example of a fortification based on the control of water. It was built between 1883 and 1920 and extends 135 km around the city of Amsterdam. The protection of the center of the country was ensured by a network of 45 forts and their artillery acting in concert with temporary flooding from polders and an intricate system of canals and locks.
The Wouda Pumping Station is the largest steam-pumping station ever built. It opened in 1920 and is still in operation.
