Homework
Slide 1 - Tekstslide
Climate adaptation
Temperature rises
Sealevel rises
We need to change -> adapt
Climate adaptation
Slide 2 - Tekstslide
Coastal defence
What does the Netherlands do to protect its coast
Slide 3 - Tekstslide
Slide 4 - Video
Coastal defence
What does the Netherlands do to protect its coast
Sand is an important tool for coastal defence
Slide 5 - Tekstslide
Sand suppletion
There are constant currents along the Dutch coast
These constantly move sand
Slide 6 - Tekstslide
Sand suppletion
There are constant currents along the Dutch coast
These constantly move sand
If we leave this be we would lose sand due to rising sea levels
So we need to adapt
Slide 7 - Tekstslide
Sand suppletion
There are constant currents along the Dutch coast
These constantly move sand
We supply additional sand
Slide 8 - Tekstslide
Sand suppletion
Dunes become higher
The beach becomes broader
The Netherlands becomes safer
Slide 9 - Tekstslide
Coastal defence
Dunes
Sea dikes
Storm surge barriers
Slide 10 - Tekstslide
Storm surge barriers
Movable flood barrier built to protect a river or estuary.
They can be closed with extremely high water
Slide 11 - Tekstslide
Coastal defence
Dunes
Sea dikes
Storm surge barriers
primary flood barriers
(Barrier that provides protection against high water levels in major rivers, large lakes (such as the Markermeer and IJsselmeer in the Netherlands) and the sea.
Slide 12 - Tekstslide
Dike rings
An area protected by primary flood barriers
Flood risk: once every 10.000 years
Dike ring 14
Slide 13 - Tekstslide
Risk
Chance of a disaster + Number op people at risk = risk
Slide 14 - Tekstslide
Risk
Chance of a disaster + Number op people at risk = risk
Low
Slide 15 - Tekstslide
Risk
Chance of a disaster + Number op people at risk = risk
High
Slide 16 - Tekstslide
Risk
Chance of a disaster + Number op people at risk - preparation = risk
Minder hoog dan het zou kunnen zijn
Slide 17 - Tekstslide
Dike rings
An area protected by primary flood barriers
Flood risk: once every 10.000 years
How high is the risk here?
Dike ring 14
Slide 18 - Tekstslide
Who protects us against the water?
The Dutch water board (Waterschappen)
Organization responsible for water safety, water purification and ensuring there is enough fresh water.
Slide 19 - Tekstslide
