Impact climate change scenario’s
High water levels
� Sealevel rise
� More run-off from the river in times of heavy rain
Low water levels
� Less runoff from the river in times of drought

High water levels causes a flood risk
� Assess the effects of climate change on the development of flood-prone areas outside of the protective dykes and polders of the Rotterdam – Drecht Cities area
Low water levels has an effect on fresh water supply and accessibility
� Optimize the open access and fresh water supply for the region
� Keep up the high service level in hinterland transport

Consequences of severe flooding
� (Death) Victims: unlikely
� Society in disorder: possible
� Environmental damage: not considered at this moment
� Economic loss: not considered at this moment
16
High water - developments
� Legislation regarding the areas outside the dikes.
� Discussion on the construction standards of dikes.
This is due to the rise in economic value of the inner
dike areas.
� Due to the high population density of the area early
decision making is key.

Accessibility - developments
� The interest of the Port and Rotterdam is widely
known
� Climate solutions may impact sea and/or inland
shipping
� Economic effects depend on closure frequency or
possibility to bypass the barrier (navigation lock)

Fresh water - developments
� Sources of fresh water are limited
� Climate change results in extremeties
� The water has to be shared
� May lead to more salt water intrusion in the southerndelta

Specific interests Port of Rotterdam
1. Open access is key. Some climate change solutions have negative effects on accessibility
2. Fresh water is available for now. In the future salt intrusion during extreme conditions may cause temporary inlet stops.
3. Flood risk is limited, though one should use climate proofing solutions as they materialize.
4. Determining and using a climate solution is reassuring to investors
with regard to climate change
24
The Port of Rotterdam is securing its future by
developing climate proofing
