Porosity and Permeability

Front

What is porosity?

Back

Porosity is the amount of air space between sediments.

Front

What is permeability?

Back

Permeability is the ability of water to flow through sediments.

Front

Which particle arrangement results in the greatest porosity?

Back

Well sorted and loosely packed particles result in the greatest porosity.

Front

What shape of particles is most permeable?

Back

Round particles are the most permeable.

Front

What is the relationship between particle size and capillarity?

Back

Smaller particles generally have greater capillarity.

Front

What does it mean if a material is impermeable?

Back

If a material is impermeable, it does not allow water to flow through it.

Front

How does sorting affect porosity?

Back

Well sorted sediments have higher porosity compared to poorly sorted sediments.

Front

What type of soil has the slowest water movement?

Back

Clay has the slowest water movement due to its small pore spaces.

Front

What is the effect of particle shape on permeability?

Back

Round particles allow for easier water flow, increasing permeability.

Front

What is the definition of infiltration?

Back

Infiltration is the process by which water enters the soil.
