(Gerard Gassol). This work will focus in how climate change will affect the city of Schiedam. We will study the main consequences of climate change in the Netherlands and we will focus in flood. How floods will affect the City at mid and long term. In order to do an accurate approach, we will consult various studies but specially the last KNMI’14 study, developed by the Royal Netherlands Meteorological Institute.

climate change

2. Schiedam: a history linked to
their canals

3. Floods, a problem that
is growing in frequency
and intensity
Historically, in the Rhine Meuse Scheldt
river delta, there have been important
floods due to their topography and
position.
Climate change will increase the
number and intensity of storms in that
area.
ICT and IoT can relieve the effects of
floods.

4. Climate Change
effects in the
Netherlands1. Temperature increases between
2 and 3 degrees average.
2. Mean precipitation increases. Less
rain days but with more intensity.
Rise of storm events
3. Sea level rise in all the
Netherlands coast

5. Local reality in Schiedam
1
Under the sea
level
Much of the city is below the
sea level. All water that falls
in the city must be pumped.
2
Subsidence of City
surface
Schiedam is settled on layers
of clays and vegetable soil.
Some part of this terrain sinks
an average of 2mm/year.
3
Timber piles
foundations
Some of the buildings have
timber piles, which will be
affected due to dry periods

6. Consequences
Higher costs to deal with floods: More
water to be pumped to higher level
More inconveniences for Schiedam
citizens

7. Vulnerability
Map
Not a flood model
Based on:
● Land Use
● Inundation Potential Risk
● Long Term Potential Risk
Comparison with:
● Social Data
● N&H flood model

8. Data involved
A Water System
Ponds, channels, pumps and
drainage water paths
B Sewer System
Pipes and tunnels designed
to collect surface runoff water
C Ground Level
Topography map for all the
area of study

9. Data involved
D
Ground
Subsidence
Between 1 and 3 mm/year
E
Buildings
foundation type
Timber piles as foundations.
F Land Use
Schools, Hospitals, electrical
infraestructure as vulnerable.

10. Result
VULNERABILITY = 10*[A] – 10*[B] + 60*[C] + 15*[D] + 10*[E] + 15*[F]

11. Actions

Collaborative basins
Mobile App
Gobernavility
Hydro-sensitive urbanism

12. Water collection points
Collaborative basins Green roofs

13. Mobile App
Be aware

14. Be aware
Marketing on climate

Awareness does not mean
consciousness

16. Get involved
Report incidences
Accurate location and time
Potentially more reports → Gain of Flood Coins
Virtual currency
Incentiviate collaboration
Tool to reward good citizens

17. Virtual Currency
Obtaining Flood Coins
Circulating Flood Coins
Benefits for citizens and City
Council

18. Governance
City Council and citizens
must collaborate
Modification of taxes
Collection of taxes must adapt to
Virtual currency system. Change of
mentality in tax collection
Adaption of building law
Water collection points installation
to be compulsory in the
construction of new buildings

19. Hydro-sensitive urbanism
1
Architectural
adoptions
New architectural
modifications of the city
should be thought as tools to
fight against floods
2
New pavement
type
Exists technologic pavement
which absorbs water and
pour it slowly
3
Sewer system can
help
Modifications in the sewer
system, separating grey
waters, can help enormously
