The effects of flooding can be devastating for those living in affected areas, with property and infrastructure damage often being the most significant cost incurred. However, there are many ways that civil works can be used to mitigate the impact of flooding for both urban and rural communities.
Here are five ways civil works are improving Australian cities' flood management strategies.
1. Raising Roads
One way to prevent flooding is by raising roads above the level of any potential floodplain. This not only protects vehicles from damage but also allows emergency personnel access during an emergency situation like a flood or storm surge.
2. Enhanced Drainage Systems
The first line of defence against flooding is a well-designed and maintained drainage system. Civil works play a vital role in constructing efficient drainage systems that effectively divert stormwater away from populated areas and reduce the likelihood of flooding. Advanced civil works now employ technologies like computer simulations to predict water flow, which helps in designing highly efficient drainage systems.
3. Flood Levees And Dykes
Flood gates and barriers are another way to manage flooding and protect residential areas from flood damage. These structures can be used to restrict the flow of water into an area or prevent it from exiting completely. Civil works teams apply sophisticated engineering techniques to build these structures, ensuring they are robust and durable enough to withstand extreme weather events.
4. Sustainable Urban Drainage Systems (SUDS)
Civil works are increasingly focusing on the implementation of Sustainable Urban Drainage Systems (SUDS). These systems aim to mimic natural water management processes by slowing down the flow of water, allowing for natural infiltration into the ground, and storing excess water for future use. SUDS not only improve a city's flood management but also contribute to the city's overall sustainability.
5. Water Storage And Retention
To combat the dual challenges of flooding and water scarcity, civil works have started to construct water storage and retention systems. These structures, which can range from small rainwater tanks to large reservoirs, help to capture and store excess rainwater during storm events. This captured water can then be slowly released back into the drainage system, preventing overloading and potential flooding. Additionally, stored water can be used for various purposes during drier periods, contributing to water sustainability.
Through these efforts, civil works are not only protecting Australian cities from the risks and impact of floods but also contributing to a more sustainable future.
