What is permeability?
" Permeability is defined as the property of a porouse material which permits the passage of water or other fluids thorough it's interconnecting voids. "A material having the continuous voids is called permeable. Gravels are highly permeable while stiff Clay is the least permeable, and hence such a Clay may be termed impermeable for all purpose.
1. Laminar flow .
2. Turbulent flow.
In laminar flow , each fluid particle travels along a definite path which never crosses the path of any other particle .
In turbulent flow , the paths are irregular and twisting, crossing and recrossing of each particle is occures.
Some important fields where permeability and seepage study is very essential . Out of which some are below.
1. In case of saturated compressible soil to determine the rate of settlement of foundation of any structural element.
2. To calculate the seepage of water through the body of Earth dam , and stability of slopes .
3. In calculation of uplift pressure under hydraulic structure and their safety against different water pressures .
4. Ground water flow towards open well and tube well and drainage of soil in diff conditions.
