Twenty-six percent of the Netherlands lies below sea level, i.e. below NAP. Without dunes or dikes, 66% of the Netherlands would be flooded on a regular basis. Source: Watermonitor 2001


The Dutch have been reclaiming land since as early as 1533. The first polder was made by draining the Achtermeer south of Alkmaar. For centuries, the creation of new agricultural land was the main reason for making polders. Water in NL 2004-2005

After the Second World War, however, reclaimed land was mainly a way of finding new land for the growing population


An prime example is the IJsselmeer dam which allowed almost half of the old Zuiderzee to become dry land.

The Netherlands has a total of 3,500 kilometres of primary flood defences. These consist of 1,430 km of river dikes, 1,017 km dikes around lakes, and 430 km dikes and 260 km dunes for coastal defense. http://www.waterland.net/

After the floods in the province of Zeeland in 1953 the government set up a project called the Delta Plan to protect Zeeland from future floods. Water in NL 2004-2005


The Delta Works cost a total of EUR 5.4 billion. Including the creation of the Maeslant barrier which also protects flood prone Holland from surges during storms. http://www.deltawerken.com

To keep water manageable, a policy is being pursued that offers more room for water (see section 12). This will allow the water to follow a more natural course and further reduce the risk of flooding.

In many parts of the Netherlands, there is a slow, natural fall in ground level. This subsidence has various causes. So not only will the sea level rise but Holland is slowly sinking. Water in NL 2004-2005
