Hazard Breakdown
Climate Hazard Breakdown for Mannum Waters
Flood
Mannum Waters faces a moderate risk of flooding, primarily from the Murray River. Riverine flooding can inundate low-lying areas and impact properties close to the riverbank.
Key drivers:
- ·Increased rainfall intensity
- ·Riverine overflow
Bushfire
The bushfire risk in Mannum Waters is relatively low due to the cleared land and proximity to the river. However, surrounding areas with vegetation pose a potential threat.
Key drivers:
- ·Dry vegetation in surrounding areas
- ·Wind patterns
Heat
Mannum Waters experiences high temperatures during summer, increasing the risk of heatwaves and heat stress, particularly for vulnerable populations.
Key drivers:
- ·Rising average temperatures
- ·Increased frequency of heatwaves
Coastal
As an inland suburb, Mannum Waters has a negligible risk from coastal hazards such as sea level rise and coastal erosion.
Key drivers:
- ·Not applicable
Wind
Moderate wind risk — gusty northerly winds
Storm
Moderate storm risk — occasional thunderstorms
Social
Moderate social stability
Energy
Moderate energy costs — summer cooling

Learn moreAbout Mannum Waters's Climate Risk Profile
Mannum Waters, located in South Australia, is susceptible to several climate-related risks. The most significant threat is riverine flooding due to its proximity to the Murray River. Increased rainfall intensity and potential river overflows can lead to inundation of low-lying areas, impacting properties and infrastructure.
Heatwaves pose another considerable risk to Mannum Waters. Rising average temperatures and more frequent heatwave events can cause heat stress, particularly for vulnerable residents such as the elderly and those with pre-existing health conditions. The urban heat island effect, although limited in this area, can further amplify these risks.
Bushfire risk is relatively low compared to other regions in South Australia, but surrounding areas with vegetation still present a potential threat. Dry vegetation and wind patterns can contribute to the spread of bushfires, posing a risk to properties on the outskirts of the suburb.
Coastal risks are negligible for Mannum Waters due to its inland location. Sea level rise and coastal erosion do not pose a direct threat to the suburb.
