permeability in soils definition
Permeability in Soils - Definition

Permeability is the measurement of the soil’s ability to allow water to flow through its pores or voids

importance of permeability
Importance of permeability
  • Applications in Civil Engineering
  • Design of earth Dams
  • The slope stability (mountains stability)
  • Retaining walls
  • Filters
  • Underground seepage and aquifers
permeability tests constant head vs falling drop head
Permeability TestsConstant Head vs. Falling (drop) Head

The falling head test is used both for coarse-grained soils as well as fine-grained soils

The constant head test is used primarily for coarse-grained soils

mechatronics on permeability
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.

Permeameter with ultrasonic sensor and NXT to measure water volume and time

my expectations
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
