This video introduces the use of flownets in geotechnical engineering. Water flow through soil has a significant impact on the soil properties and behaviour - these impacts are often assessed today using proprietary software. However, an ability to construct a basic flownet is a valuable first step in evaluating ground water flow problems and is particularly useful for getting a “feel” for how the problem should be modelled. The fundamentals of constructing a flownet and its geotechnical applications are the discussed in this video.
