The short answer is: not very. Permeability is a characteristic found in many things such as plants, rocks, soils, and the cells of our bodies. Scientists measuring this characteristic use the letter "K" (also known as hydraulic conductivity) to describe the ability of water to travel through spaces between particles found in nature (in our case, clay soil).

To keep things simple, K measures how fast water moves through a sample over time. Results are often shown in feet/day or centimeters/second.

Methods of measuring K vary from complex to simple and can be done in the field using specialized equipment or by conducting experiments in the lab.

Clay soil's K is approximately 0.01 to 0.001 feet per day: K=0.01-0.001. For comparison, K=1.0-10.0 ft/day for peat.

Yes, I think clay is permeable, although not so much as sand or gravel.

It's both high and low depending on how much water is takin from a well and how much it rains into the soil

What affects permeability of soil?

A big factor is compaction. Another factor is clay content. I noticed that salinization affects permeability, too. The fields in Iraq have been irrigated for millennia. When it rains, the first few inches of dust turn to thick, sticky mud and the soil beneath remains dry.


Does clay have high permeability?

No. Clay particles are very small and tend to attract other clay particles to from a matrix. Permeability refers to the ability of a gas or liquid to flow through a material. Because clay forms a tight matrix, gas and liquids flow very slowly through clay. Loose sand has high permeability


What surface soil type has the slowest permeability rate and is most likely to produce flooding?

Generally, it's the type with the most clay at the surface. Clay type soils are least permeable, especially when disturbed or compacted when wet by agricultural or forestry heavy machinery. The permeability rate of soil can be somewhat inversely related to it's porosity. Clay soils are very porous, since they can hold more water than a sandy or loamy soil type. However, rate of infiltration and permeability are slow. it can take a long time for water to soak into the soil (rain water entering soil prevents over land flow and therefore flooding). Sandy soils are able to quickly absorb water and generally have higher permeability. Caveat - Sandy soils, in temperate and subtropical climates, often have a limiting clay layer somewhere below the surface that restrict water flow through the soil profile at certain depths. Hope this helps... Bill


How does the permeability of soil and rocks affect the flow of groundwater?

Permeability is when water can pass through different types of soil and rocks. Therefore the permeability affects the soil and rocks because if the soil or rock is PERMEABLE then the groundwater can easily flow through it :)
