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.
