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.

Section 2: Scenarios


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

Section 2: Inter-related parameters

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

(WG178)

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

Flexibility is Key


OCTOBER 2016 17

Flexible Solutions


OCTOBER 2016 18

Example: Docks

Norconsult - Floating Docks Concept


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

Flexible Solutions

● NO REGRET

● Managed Realignment/Green Belt

● Re-organisation of port infrastructure (critical assets)

● Behavioural measures (traffic management plan/maintenanceroutines)


OCTOBER 2016 20

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, highwater level, high wind and/or waves, debris in harbour etc

• Low key measuring devices

• Logg-keeping of damage and obstacles
