THIS PPT COVERS ABOUT WIND EROSION TOPICS COVERED ARE :DEFINITION OF WIND EROSION FACTORS AFFECTING WIND EROSION AND MECHANICS OF WIND EROSION

1. WIND EROSION
PRESENTATION BY
UTKARSH JAIN

2. WIND
EROSION
 NATURAL PROCESSOFTRANSPORTATIONAND DEPOSITION
OF SOIL BYWIND.

3. FACTORS
AFFECTING
 MAJOR FACTORS :
1. CLIMATE .
2. SOIL.
3. VEGETATION.

4. MECHANICS
1.INITIATIONOF MOVEMENT
 SOIL PARICLESARE DETATCHED FROMTHEIR PLACE.
2.TRANSPORTATION
• SUSPENSION , SALTATIONAND CREEPARETHREETYPES OF
SOIL MOVEMENT.
• SUSPENSION:OCCURSWHENVERY FINE DUST PARTICLESARE
LIFTED.
• 3-40% SOILWEIGHT IS CARRIED.

5. MECHANICS
 SALTATION :CAUSED BY PRESSUREOFWIND & COLLISIONOF
PARTICLES.
 TRAVELAPPROX 4TIMES MORE DISTANCETHAN HEIGHT.
 50-75% SOILWEIGHT IS CARRIED .
 SURFACE CREEP: PARTICLESTOO HEAVYTO BE LIFTED MOVE
THROUGH CREEP.
 5-25% SOILWEIGHT IS CARRIED.

3. DEPOSITION : OCCURSWHEN:
 GRAVITATIONAL FORCE >FORCES HOLDING PARTICLE IN AIR.
