www.overstroomik.nl

Aims

After studying this section, you will be able to:

• Describe how river discharges are likely to change in the future;
  
• Explain how the Netherlands deals with high and low river discharges.
  

Living near the water

Historically cities were built near waterways: 

• Easy to transport goods and people;
  
• Water for crop farming;
  
• Opportunity to fish;
  
• High risk of flooding.

Living near the water

Solutions against flooding: 

• Building dwelling mounds (terps);
• Constructing dykes.

Regional government was needed to control the water level;

Water authorities were formed to maintain dykes at a local level.

Urbanization

Growth of cities; rivers had to be tamed:

• Channelizing rivers;
• Constructing higher dykes.

In 1995 it almost went wrong...

• Evacuation of people;
• Outer-dyke areas flooded.

From Bolland to Holland...
