Presentation Transcript

  1. Permeability in soils How fast does water travel trough soils? • By • Eduardo Suescún • PhD Candidate, GK-12 Fellow • Civil Engineering Department • NYU-POLY

  2. Permeability in Soils - Definition Permeability is the measurement of the soil’s ability to allow water to flow through its pores or voids

  3. Importance of permeability • Applications in Civil Engineering • Design of earth Dams • The slope stability (mountains stability) • Retaining walls • Filters • Underground seepage and aquifers

  6. Permeability TestsConstant Head vs. Falling (drop) Head • The falling head test is used both for coarse-grained soils as well as fine-grained soils Source: http://echo2.epfl.ch/VICAIRE/mod_3/chapt_8/main.htm The constant head test is used primarily for coarse-grained soils

  7. Mechatronics on Permeability • A Ultrasonic Sensor is used to find out where objects are! Using this sensor it is possible to detect an object and measure how far it is.

  8. Advantages of mechatronics in permeability test • http://earthlearningidea.blogspot.com/2008/04/great-soil-race.html • Permeameter with ultrasonic sensor and EV3 to measure water volume and time

  9. My expectations • The ability to define and understand permeability in soils. • The capacity to identify differences in size between gravel, sand, and clay • The ability to identify advantages and disadvantages of having a highly permeable soil • The ability to understand porosity in soils • The ability to understand the functionof sensors, and mechatronics importance

  10. THANK YOU !
