1.2 Sheet erosion. This is the type of erosion that results from runoff that spreads across the soil surface during rainfall (i.e. when the infiltration rate has been .. 7e.pdf. FAO. 2008. Visual Soil Assessment (VSA) Field Guides, Food and Agriculture. Organization of the United Nations, Rome, Italy. Available from .
Soil erosion is a major problem in. Agriculture. Tonnes of soil are lost from fields every year. This not only reduces crop production, the soil acts as a pollutant to rivers, lakes, and other water systems. Soil erosion can be controlled with the proper techniques. This article describes soil erosion and some methods of
Sheet erosion is less apparent, particularly in its early stages, than other types of erosion. It can be serious on soils that have a slope gradient of only 1 or 2 percent; however, it is generally more serious as slope gradient increases. Rill erosion is the removal of soil through the cutting of many small, but conspicuous,
18 Dec 2013 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
This leaflet explains the different types of erosion on the north coast. Water erosion. The north coast's high rainfall makes the region's soils vulnerable to water erosion. High intensity destructive storms are responsible for a significant proportion of the erosion. Splash erosion. Splash erosion is the first stage of the erosion.

Types of Soil Erosion. ?Rain drop or splash erosion: ? Erosion preceded by the destruction of the crumb structure due to the impact of falling raindrop on the surface of soil is termed as splash erosion. ?Sheet erosion: ? It is the fairly uniform removal of soil in thin layers from the land surface, often scarcely perceptible

2.1.1.1 Water Erosion. The major types of water erosion are: Splash – When vegetative cover is stripped away, the soil surface is directly exposed to raindrop impact. Splash erosion results when the force of raindrops falling on bare or sparsely vegetated soil detaches soil particles that can easily be transported by runoff.
Soil erosion occurs when soil is removed through the action of wind and water at a greater rate than it is formed. SOIL. The soil covering the surface of the earth has taken millions of years to form and we must learn to respect it. Soil is formed at a rate of only 1 cm every 100 to 400 years and it takes 3 000 to 12 000 years to
