Climate change is one of the most concerning problems facing the millennial generation, aside from worrying about the current salary grade. We can feel the effects—in the weather, in the air, and even in the way we live. However, how we live is also interconnected to the infrastructures we navigate. Sadly, the effects of climate change will also affect it.
You may ask, how is infrastructure affected by climate change? Well, we’ll answer this in the article below!
Bolstered Bridges
Climate change has caused many environmental factors to change. Professor of Practice Wije ‘Ari’ Ariyaratn, an expert in bridge engineering, recommends strengthening bridge infrastructure. This will help futureproof bridges for the stressors caused by climate change.
Roads are integral, especially for transportation. After all, we cannot go to Point B from Point A without a road. Despite the inevitable degradation due to daily use, roads are designed for a long service life, for up to a century. With the proper maintenance, it is possible for existing bridges to perform well and remain safe.
Climate change can also externally affect the bridges; especially their safety, longevity and performance. At the worst-case, it can result in loss. This is due to extreme temperatures, higher flood levels and fires.
Cities can produce new building and infrastructure codes to adjust to climate change. This way, engineers will develop new techniques to help review bridges for any changes caused by climate change and then ideate and execute cost-effective methods that improve bridge sustainability and performance.
Higher Costs Due To Rainfall
A lot of scenarios under climate change is stressful. One of the most noticeable is increased rainfall (precipitation). Unfortunately, that can result in more infrastructure damage, as moisture can lead to dangerous organisms forming in the site, which can affect its residents. Soil-run off is also another negative effect of climate change through increased rainfall.
On the contrary, less rain (precipitation) also has its own problems. This means there’s a drop of water flow. The temperature of air and water willresult in accelerated evaporation. There’s also the matter of asset corrosion; the term itself is no joke.
The rise of sea level can also affect water supply; saltwater will intrude into groundwork aquifers. This will interrupt the flow of water that is not from the sea. This also means an unbalanced ecosystem.
In Australia, a dramatic drop in rainfall is the status quo. Australia’s urban centers will still experience a lengthy and dramatic decrease of rainfall. Unfortunately, desalination is the answer to somehow alleviate this problem, despite it being costly.
For infrastructure, this means lower costs. How? Easy. This means maintenance costs need to be higher and there will be more costs to maintain water treatment systems.
Raised Bridges
The landscape is also changing. Literally. Thus, elevated bridges and roads will become a thing. Due to their nation, maintenance will pile on costs. At worst, they can even require replacements. As such, those who will handle it need to be more careful about the impact on the natural environment. One way is to use minimal amounts of concrete in construction.
Stress on Infrastructure
Cities with too much people in it will also reap the consequences. Urban infrastructures will have to invest in integral waterproofing because of the stress on infrastructure. Flooding will also make the situation worse.
Wrapping Up
Despite negative impacts, man is built for evolution and survival. It’s also a chance and opportunity for engineers and common people to change their ways and adapt – because the damage man has inflicted on nature is taking a toll. Thus, it is an incentive to become better stewards of the environment.
