What is the relationship between porosity and infiltration?

Soils with higher porosity have more pore space and a higher infiltration rate than those with lower porosity.

What is infiltration and how is it affected by porosity and permeability?

Permeability is the ability of soils to transmit water and air through its layers. Infiltration is the rate at which water can move through a soil and its layers. It can be measured as the saturated hydraulic conductivity of a soil.

How does permeability affect infiltration?

The permeability of a soil can be determined by calculating its infiltration rate. Soils with sandy textures have large pore spaces that allow rainfall to drain very quickly through the soil. Sandy soils are known to have high permeability, which results in high infiltration rates and good drainage.

What is the relationship between porosity permeability and good aquifers?

The properties that make a good aquifer are those that increase the storage of water (porosity) and increase the flow of water (permeability) within that layer. Porosity is the proportion of empty space in a rock. Permeability is a measure of the ease with which liquids and gases can pass through a rock.

What does high porosity and permeability in soil mean?

That means that all it is simply a layer of soil or rock that has a reasonably high porosity and permeability that allows it to contain water and transfer it from pore to pore relatively quickly and all of the pore spaces are filled with water.

How is permeability and infiltration related to soil health?

This resource looks at how different soil health factors affect the permeability and infiltration of the soil. Generally, a good soil for crop production contains about 25 percent water and 25 percent air by volume. This 50 percent is referred to as pore space.

How are permeability and porosity of limestone reservoirs related?

In limestone reservoirs, fractures are principally micro-fractures, the percentage of connecting pores to total pores is positively correlated with permeability; while in dolomite reservoirs, there is not such an obvious relationship between the percentage of connected pores to total pores and permeability.

How does the porosity of an aquitard affect water flow?

In fact, in the ground they often act as a barrier to water flow and separate two aquifers. The one key exception is that aquitards can have high porosity and hold lots of water however, due to the their low permeability they are unable to transmit it from pore to pore and therefore water cannot flow within an aquitard very well.
