Falling Head Permeability Test | Procedure and Data Analysis #education #experiment

This video shows how to perform a falling head permeability test for fine-grained soil. This test is typically performed on fine-grained soil with low permeability. The soil sample must be first saturated, which takes several days so that a laminar steady water flow is established. The test takes only a few minutes, it is necessary to measure the amount (volume) of water over time. Darcy's law is then used to estimate the coefficient of permeability. Watch this video to learn how to use the data from this test to estimate the water flow under a structure https://youtu.be/Q5wz0DGnTgA. The fundamentals of water flow in soil mass including liquefaction and quick conditions are described in this video https://youtu.be/8ap5zUbWU1o, while the principles of vertical water flow in soil are explained using a practical example in this video https://youtu.be/neLmQpEc-AI. #engineering #science Other tests: Pocket penetrometer test https://youtu.be/kWaCaKE7jXc.
