The image above represents quantity of soil moved.

To compute for quantity of soil moved, two essential parameters are needed and these parameters are **Excess Wind Velocity (v _{w})** and

**Particle Diameter (d**

_{p}).The formula for calculating quantity of soil moved:

Q = v_{w}³ . d_{p}

Where;

Q = Quantity of Soil Moved

v_{w} = Excess Wind Velocity

d_{p} = Particle Diameter

Let’s solve an example;

Find the quantity of soil moved when the excess wind velocity is 12 and the particle diameter is 20.

This implies that;

v_{w} = Excess Wind Velocity = 12

d_{p} = Particle Diameter = 20

Q = v_{w}³ . d_{p}

Q = (12)³ . (20)

Q = (1728) . (20)

Q = 34560

Therefore, the **quantity of soil moved **is **34560.**

**Calculating the Excess Wind Velocity when the Quantity of Soil Moved and the Particle Diameter is Given.**

v_{w}³ = ^{3}√^{Q} / _{dp}

Where;

v_{w} = Excess Wind Velocity

Q = Quantity of Soil Moved

d_{p} = Particle Diameter

Let’s solve an example;

Find the excess wind velocity when the quantity of soil moved is 30 and the particle diameter is 10.

This implies that;

Q = Quantity of Soil Moved = 30

d_{p} = Particle Diameter = 10

v_{w}³ = ^{3}√^{Q} / _{dp}

v_{w}³ = ^{3}√^{30} / _{10}

v_{w}³ = ^{3}√3

v_{w}³ = 1.442

Therefore, the **excess wind velocity **is **1.442.**

**Calculating the Particle Diameter when the Quantity of Soil Moved and the Excess Wind Velocity is Given.**

d_{p} = ^{Q} / _{vw³}

Where;

d_{p} = Particle Diameter

Q = Quantity of Soil Moved

v_{w} = Excess Wind Velocity

Let’s solve an example;

Find the particle diameter when the excess wind velocity is 5 and the quantity of soil moved is 40.

This implies that;

Q = Quantity of Soil Moved = 40

v_{w} = Excess Wind Velocity = 5

d_{p} = ^{Q} / _{vw³}

d_{p} = ^{40} / _{5³}

d_{p} = ^{40} / _{125}

d_{p} = 0.32

Therefore, the **particle diameter **is **0.32.**
