Groundwater Porosity & Permeability

Front

What is permeability?

Back

Permeability is the measure of how easily water can flow through an aquifer.

Front

How does particle size affect permeability?

Back

The larger the particle size, the faster the permeability rate.

Front

What happens to water movement as grain size increases?

Back

The larger the grain size, the faster the water will move through the soil.

Front

Which type of soil has the greatest permeability?

Back

Soil with larger particles, such as sand, has the greatest permeability.

Front

Why are sand sediments more permeable than silt sediments?

Back

Sand grains are larger than silt grains, allowing water to flow through more easily.

Front

Define porosity.

Back

Porosity is the measure of the empty spaces in a material, which can hold water.

Front

What is the relationship between porosity and permeability?

Back

While porosity refers to the amount of space available for water, permeability refers to how easily water can flow through those spaces.

Front

What type of soil typically has the lowest permeability?

Back

Clay soil typically has the lowest permeability due to its small particle size.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water.

Front

How does soil compaction affect permeability?

Back

Soil compaction reduces the size of the pores, which can decrease permeability.
