Dry periodes and heat waves

Sometimes we have too much water, but in the summer more heat waves and shortage of water.

Consequences for the Netherlands

• Shortage of fresh water
  
• Intrusion of seawater --> salinization
  

Why is the IJsselmeer essential in summer for the Netherlands?

Heat

Heatstress

(meaning higher numbers of people becoming sick and dying, less productivity and more aggression) 

Effect of urban-heat island is enhanced by urban petrification.

Heat

Answer is more greening of the city

• shadow
• cooling by evaporation - rainwater can sink into the soil when there is heavy rain
  
  

(climateproof design)

Guidebooknumbers

Rivers

There are three kinds of rivers:

1. Rain river
   
2. Glacier river
   
3. Mixed rivers
   

Regime and flow rate

Verschil in waterafvoer: regiem

Totale hoeveelheid water op een bepaald punt: debiet. 

Regime of the Rhine and Meuse

Flow rate

Regime

During drought, salinization can occur. NL may then run short of fresh water. Where does NL have a supply of fresh water?

1. In the Meuse
2. Lake IJssel
3. In Germany
4. In the Rhine

How does a heat island form?

1. Greening
2. Petrification
3. Salinization
4. Evaporation
