Scalded Landscape, Western Queensland

Soil erosion is a widespread problem in rural and urban Queensland. If we want to save our soils, we need to understand the different types of erosion that can occur. Water erosion. Queensland’s high intensity summer rainfalls represent a significant risk of erosion by water. Raindrops hit bare soil with enough force to break the soil aggregates.

Severe Stream Bank Erosion
Severe Stream Bank Erosion

• bank soil characteristics such as poor drainage or seams of readily erodible material within the bank profile • wave action generated by wind or boat wash; • excessive or inappropriate sand and gravel extraction • intense rainfall events (e.g. cyclones). Processes of stream bank erosion The various mechanisms of stream bank erosion generally fall into two main groups, bank scour and ...

Tunnel Erosion in Marburg, Queensland
Tunnel Erosion in Marburg, Queensland

Tunnel erosion is the removal of subsoil. When water penetrates through a soil crack or a hole where a root has decayed, the soil disperses and is carried away with the flow to leave a small tunnel. Initially, the surface soil remains relatively intact but, with every flow, the tunnel becomes larger and the soil may eventually collapse and form a gully.

Water Erosion
Water Erosion

Soil erosion by water (aka 'water erosion') is the result of rain detaching and transporting vulnerable soil, either directly by means of rainsplash or indirectly by rill and gully erosion.

Wind Erosion
Wind Erosion

Wind erosion is a natural process that moves soil from one location to another by wind power. It can cause significant economic and environmental damage. Wind erosion can be caused by a light wind that rolls soil particles along the surface through to a strong wind that lifts a large volume of soil particles into the air to create dust storms.
