Soil Formation: How is Soil Formed [with Factors and Processes for Class 7, 8 ,9, 10]! Soil formation is a long slow process. It is estimated that an inch of soil takes 500 to 1000 years to form. Soil is constantly being formed and eroded. The soil formation is the process of weathering of rocks and minerals into regolith and [...]
In this article we will discuss about:- 1. Definition of Permeability 2. Darcy's Law (1856) of Permeability 3. Capillarity-Permeability Test 4. Permeability of Stratified Soil Deposits. Definition of Permeability: It is defined as the property of a porous material which permits the passage or seepage of water (or other fluids) through its interconnecting voids. A material having continuous voids is [...]
Determination of Coefficient of Permeability in Laboratory: 1. Constant Head Permeability Test (Coarse Grained): Water flows from the overhead tank consisting of three tubes – The inlet tube, the over-flow tube and the outlet tube. The constant hydraulic gradient i causing the flow is the head h (i.e., difference in water levels of the overhead and bottom tanks) divided by [...]
