b) According to Darcy's law for flow through porous material, the velocity is proportional to _? Before I explain to you the relation between discharge velocity and seepage velocity in soil mass you must have some knowledge of permeability and percolation of soil. Impervious Soil Equivalent Permeability in Stratified Soil The main difference between porosity and permeability is that porosity is a measurement of space between rocks whereas permeability is a measurement of how easy it is for fluids to flow between rocks.. What is Porosity. (physics) a quantitative measure of the degree of magnetization of a material in the presence of an applied magnetic field (measured in newtons per ampere squared in SI units). Porosity measures how much space is between rocks. Datum We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads.

Main Difference – Porosity vs. Permeability. 4 permeability and seepage 1. ... constant head a) Difference between the seepage and permeability? the process by which a liquid leaks through a porous substance; the process of seeping, water that seeped or oozed through a porous soil. On the other hand, Permeability gets defined as the state of quality that exists for material or membrane that results in the allowance of liquids or gases to pass through the structure. As nouns the difference between permeability and seepage is that permeability is the property of being permeable while seepage is the process by which a liquid leaks through a porous substance; the process of seeping.

What conditions should be necessary to occur the seepage? See our User Agreement and Privacy Policy. Creative Commons Attribution/Share-Alike License; the rate of flow of a fluid through a porous material, (geology) a measure of the ability of a rock to transmit fluids (such as oil or water). 2) Seepage: In soil engineering, movement of water in soils, often a critical problem in building foundations. Seepage takes place when there is difference in water levels on the two sides of the structure such as a dam or a sheet pile as shown in Fig. If the soil is impermeable, will the phenomena of seepage will have happened? hA = total head Water Flow Permeability Civil Engineering Department 91 Now customize the name of a clipboard to store your clips. If the soil is impermeable, will the phenomena of seepage will have happened? Hence, the difference between the flow of water through rock or concrete is one of degree. h = hA - hB Overview of Underground W.T.

Permeability 91 Permeability and Seepage Topics 1. Laboratory and Field Tests Clipping is a handy way to collect important slides you want to go back to later. Key Differences between Porosity and Permeability Porosity gets defined as the quality of getting porous that is having shiny or small holes within a structure. Hence, the difference between the flow of water through rock or concrete is one of degree. Seepage depends on several factors, including permeability of the soil and the pressure gradient, essentially the combination of forces acting on … Flow of water through soils is called seepage. a) Difference between the seepage and permeability?
