- Description
- According to the most recent International Panel on Climate Change (IPCC) report, warming of the climate system is unequivocal, and this warming may lead to increased risk of breakdown of infrastructure networks due to extreme weather. A key means of reducing future risk exposure is implementation of effective climate change adaptation strategies for critical infrastructure assets. However, before such strategies can be put in place, we must first understand the extent of potential climate change impacts on our infrastructure. The work described in this paper examines climate change impacts for timber power pole networks. These power pole networks represent important critical infrastructure assets worldwide, with five million timber power poles currently in service across Australia worth over $10 billion, and approximately 200 million treated power poles in service in the United States. Despite the scale and value of these critical infrastructure assets, limited research has been carried out examining climate change impacts for power pole networks. The study described herein examines this area using a Monte-Carlo event-based sequential model, which incorporates structural reliability, deterioration, climactic effects and network maintenance. The hazards of interest are storm winds and timber decay - both of which may worsen due to a changing climate. The results are presented in the context of a notional network of one million power poles. Impacts are examined across five Australian regions. The analysis indicates that climate change impacts can be significant, however, the impacts were also found to be highly regionally variable.
