If the soil is impermeable, will the phenomena of seepage will have happened? b) According to Darcy's law for flow through porous material, the velocity is proportional to _? The CHAPTER 4 Discharge & Seepage Velocity of Soil, Coefficient ... Get Free Permeability And Seepage Exam Questions Answers porewater pressure and the effective stress cancel out each other. Laboratory and Field Tests Theory 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. 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). hA = total head Prof. Khalid R. Mahmood (PhD.) College of Engineering Hence, the difference between the flow of water through rock or concrete is one of degree. Permeability What conditions should be necessary to occur the seepage? 4 permeability and seepage 1. 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. h = hA - hB Civil Engineering Department Water Flow W.T. Prof. Khalid R. Mahmood (PhD.) Permeability If you wish to opt out, please close your SlideShare account. Porosity measures how much space is between rocks. Permeability and Seepage Porosity and permeability are both properties of rocks and soil. Seepage depends on several factors, including permeability of the soil and the pressure gradient, essentially the combination of forces acting on … a) Difference between the seepage and permeability? Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Flow of water through soils is called seepage. Because there is the use of the term coefficient of permeability and percolation in derivation. 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. University of Anbar ... constant head 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. the process by which a liquid leaks through a porous substance; the process of seeping, water that seeped or oozed through a porous soil. In seepage problems the velocity of flow is very small and the velocity head is negligible in comparison with the pressure and elevation heads. Hydraulic conductivity is another term used for permeability, often in environmental engineering literature.
