7. PIANC WG 178 - AIMS
Working Group on climate change adaptation for maritime and inland port and
navigation infrastructure: International guidelines for adaptation
Objectives
● to develop an approach to climate change adaptation planning and delivery for
maritime and inland port and navigation infrastructure;
● to refer to the PIANC TG3 report on climate impacts (which is assumed to be
subject to updating as necessary) indicating key regional differences as far as
practicable;
● to collate other existing information on climate projections where this is required
to meet the WG objectives;
● to generate a toolbox of adaptation options including non-structural (e.g.
management) as well as structural measures;
● to evaluate the effectiveness of different adaptation options in typical or generic
climate change scenarios;
● to understand and provide guidance on addressing challenges; and
● to provide a guidance framework for decision making.

13. Section 2: Scenarios
CLIMATE CHANGE ADAPTATION FOR PORTS - PIANC WG 178,
OCTOBER 2016 13
Emission scenarios +++
1. Choice of IPCC scenario:
RCP2.6, 4.5, 6.0, or 8.5
2. Choice of projection
conservatism within the
chosen scenario: low,
medium or high
3. Choice of time frame: 20,
50, 100 or 200 years
4. Choice of uncertainty value
to be included: lower, middle
or higher band

14. Section 2: Inter-related parameters

15. So, what does all this mean for developing a
toolbox of measures?
● Need to think about existing as well as new infrastructure
● Need structural and non-structural measures: planning-based solutions, education, and
operational or maintenance changes can all provide ‘quick wins’
● Need short term or interim as well as long term measures
● Need flexible, adaptive solutions that respond to monitoring: monitoring is key!
● Need low as well as high tech solutions
● Need low as well as high cost solutions

16. Adaptation Options – Structural and non-
structural
● Physical
• Engineered
• Raise flood defence
• Technological
• Improve pumping capacity
• Service based
• Improve maintenance of drains
● Social
• Educational
• Raise awareness
• Information
• Improve monitoring
• Behavioural
• Traffic management plan
● Institutional
• Economic
• Penalties for non-compliance with minimum standard
• Law
• Revise relevant standards
• Policy
• Flood risk management plans

17. Flexibility is Key

18. Flexible Solutions
CLIMATE CHANGE ADAPTATION FOR PORTS - PIANC WG 178,

Example: Docks

19. Norconsult - Floating Docks Concept
CLIMATE CHANGE ADAPTATION FOR PORTS - PIANC WG 178,
OCTOBER 2016 19
Low water:
- Good accesss
- Deeper water
- Increased surface
area
- Storage area
inside docks
High water (inc SLR):
- Protection from
wave attack
- Good access

20. Flexible Solutions
● NO REGRET
● Managed Realignment/Green Belt
● Re-organisation of port infrastructure (critical assets)
● Behavioural measures (traffic management plan/maintenance
routines)

21. Monitoring!!
● Site-specific monitoring in conjunction with climate change
adaptation of port planning and port operation is key and refers
mainly to the following aspects:
• Monitoring of meteorological and hydrological phenomena
• Monitoring of climate related structural damages and operational
obstacles
• Monitoring of the climate change adaptation process in the harbour itself
● All data is valuable, not only state of the art measuring stations.
• Logg-keeping of occurances of climatic phenomena, e.g. Fogg, high
water level, high wind and/or waves, debris in harbour etc
• Low key measuring devices
• Logg-keeping of damage and obstacles
