What is rain splash erosion?
What is rain splash erosion?
Splash erosion or rain drop impact represents the first stage in the erosion process. Splash erosion results from the bombardment of the soil surface by rain drops. Rain drops behave as little bombs when falling on exposed or bare soil, displacing soil particles and destroying soil structure.
What is rain splash in geography?
Rainsplash. A close-up view of a single raindrop as it redistributes soil and water. Rain may move soil directly: this is known as ‘rainsplash erosion’ (or just ‘splash erosion’).
What are the 4 types of water erosion?
There are four main types of water erosion: inter-rill erosion, rill erosion, gully erosion, and streambank erosion.
Where does splash erosion happen?
Splash Erosion When rain falls vertically on a flat surface, splash ero- sion is equal in all directions. On a slope, more of the soil is splashed downhill than uphill; and in a wind-driven rainfall, splash movement depends on wind direction and slope steep- ness.
How does rainwater cause soil erosion?
The splashed particles clog soil pores, effectively sealing off the soil surface and leading to poor water infiltration. Instead of soaking into the soil, rainwater collects and moves down-slope in sheet or rill erosion, forming gullies and carrying soil particles.
What are the 5 types of water erosion?
These are inter-rill erosion, rill erosion, gully erosion, and streambank erosion.
What are 10 types of erosion?
The different soil erosion types are explained below.
- Rain Drop or Splash Erosion.
- Sheet Erosion.
- Rill Erosion.
- Gully Erosion.
- Stream Bank Erosion.
- Due to Soil Texture.
- Slope.
- Intensity or Amount of Rainfall.
What is the significance of rain drop in soil erosion?
The kinetic energy of raindrops causes surface sealing and crust formation that reduces soil infiltration and produces surface flow, and this is why vegetation is the best soil erosion control strategy (Francos et al., 2016).
How is splash erosion controlled?
The protecting role of vegetation is the base for many erosion control, soil conservation, and rangeland management measures. Vegetation cover reduces splash erosion due to interception of rainfall, decreases overland flow, and improves infiltration of precipitation and runoff water into the soil.
How does rainfall impact erosion?
As rainfall is the major driver of soil erosion which has direct impact on separation of soil particles, decomposition of soil aggregates and migration of eroded sediment, the amount of soil erosion caused by erosive rainfall accounts for most of the total erosion.
What type of erosion is splash erosion?
Splash erosion. Splash erosion is the first stage of the erosion process. It occurs when raindrops hit bare soil. The explosive impact breaks up soil aggregates so that individual soil particles are ‘splashed’ onto the soil surface.
What are the causes of rainwater erosion?
Rainfall erosion is caused by the detachment and movement of particles from the thin soil caused by the impact of raindrops on the ground. This causes laminar erosion, as raindrops give off soil particles by the effect of kinetic energy. Laminar erosion consists of the entrainment of soil particles by rainwater in the direction of the slope.
What is the definition of sheet erosion in geography?
Sheet erosion. Sheet erosion is the removal of soil in thin layers by raindrop impact and shallow surface flow. It results in loss of the finest soil particles that contain most of the available nutrients and organic matter in the soil.
Do cover crops reduce splash erosion?
Increased foliar mass of the cover crop reduces splash erosion predictably with increasing ground coverage, and this effect is incorporated as a crop-management factor in calculating soil loss. Cover crops work by reducing splash detachment and by intercepting the splashed soil, thus limiting its trajectory movement.
