4 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, especially when caused by wind. Areas where loose, shallow topsoil overlies compact soil are most susceptible to sheet erosion. Rill erosion: A form of water erosion in which numerous very small and more or less straight channels are produced; the channels get obliterated by ordinary use. It can be removed by normal tillage operations. Gully erosion: A form of water erosion in which gullies are produced by combination of unattended rills. Stream bank erosion: Stream banks are eroded by water either flowing over the sides of a stream or scouring at the base. It is aggravated by removal of vegetation, over grazing or cultivation near the stream banks.

13 Soil Types Ability to resist erosion forces

14 Soil Has Different Properties From: Geologic Origin Composition Chemical and Physical Erosion based on: Cohesive (clay) vs. Non cohesive (sand) Density and Particle Size Permeability and Change due to COMPACTION Strength Tensile, Shear, Bearing Capacity Water Table and Saturation Vegetation and Roots

15 Geologic Origin Parent Material character and chemical composition of the parent material plays an important role in determining soil properties Glaciers, Floods, and Water Movement As glaciers pushed, they act like giant bulldozers pushing soil ahead of them. Glacial till or drift deposits resulted many tens or even hundreds of miles from where the soils were first formed. Water is also very important in moving soils. As rivers flow, they transport soil particles along. If soil is washed into a river, the smallest particles will be carried the furthest by the water as they weigh the least. Heavier particles, such as sand, will be dropped earlier. Soils dropped around streams are termed alluvial. Soils deposited in lakes are called 'lacustrine', soils deposited by rivers 'riverine' and by sea 'marine' alluvial soils

16 Composition Percent Silt, Clay, Sand, Gravel Uniform or Poorly Graded Layered Horizontally or Diagonally Densely Packed or Loose Particle Sizes
