Warning signs of collapse

 Riverbank collapse poster - river and trees
Signs of riverbank collapse are not always obvious so it's important to be aware of the risks and exercise caution at all times.

To spot a riverbank collapse, look for:

Cracking in the riverbank  
Leaning trees  
Bubbling in the water 
Fencing and signage  
Steep riverbanks with deep drop off  

Cracking in the riverbank

Cracks that are both deep and shallow are likely signs of bank instability and the area should be avoided - on foot, in vehicles or by boat.

Leaning trees

Trees, including willows and gums, leaning towards the river can be a sign of bank instability.

The root systems of these trees are weakened by the unstable soil and their weight puts pressure on the riverbank.

Bubbling in the water 

Bubbling can be an indicator of soil movement below the water surface, and hence instability.

Fencing and signage

Fencing and warning signs have been used where there has been a visible collapse, or where there is known potential for collapse or erosion. Please observe these measures and do not enter these areas.

Steep riverbanks with deep drop off

Steep riverbanks with a sudden drop off to deep water are considered to be at particular risk of collapse.
