Almost 65% of the Netherland would be flooded (sometimes) if we didn't had dikes and watermanagement!

Sea polders

• At sea level
• Sedimentation of sand and clay
• Examples at the Waddenzee and Noordzee

Peat polders

• Between 0 and 2 m below NAP
  
• Drainage of peatswamps
• Dikes surrounding the drained and compacted peatland
  
• Western part of the Netherlands
  

Reclamed lakefloors*

• Lower than 2 m below NAP
  
• Former lake or sea
  
• Dikes surrounding the desired "land" and then artificial drainage (mills or pumping statons)
• Examples: Haarlemmermeer and Beemster

*In Dutch: droogmakerijen
